[Today we welcome back SG, a twelve-year-old who previously reviewed the B2 version of the One Laptop Per Child computer. SG had a chance to examine the latest (B4) version of the OLPC machine and write a new review. As before, the review is unedited, just as SG wrote it. – Ed]

After my first review, the administrators at OLPC were kind enough to send Mr. Felten the newer model of the computer, the B4, for me to review. The difference between the two models was quite dramatic. Between new games, new applications, design changes, and a few touch ups for the system, the B4 clearly outshines the B2. I didn’t even know about a bunch of problems in the B2 until they got fixed in the B4!

The minute I picked the new computer up, I saw the physical differences. There are bumps on the handle of the B4. The B2 has none. The flip- up antenna on the B2 was encased in hard plastic, and on the B4, it’s just thick rubber. The keyboards are pretty much the same, apart from a few minor differences along the top. Once I opened it up and started it, I noted how much quicker it booted up than the B2. Then I saw the icons. The B2 has less than half the icons than the B4, which has 13!

As for games, entertainment, and the internet, this computer has bountiful resources. There were many new and fun programs. One of them, called “Block party”, is just plain old tetris with a different name. As I am not really gifted in tetris, I had a lot of fun losing repeatedly. The internet was a lot better on this newer laptop. In my last review, I complained about how slow it was and how the connection was so-so. In the B4, both of those problems have been fixed. It is quick, always connects, and is really very nice. If you don’t want to go on the web to read the new Freedom to Tinker article, “News Reader” lets you subscribe to websites’ feeds. In the games category, “Connect” is a game which can only be played on two separate OLPC laptops . The game is a little like tick tack toe. If you’ve ever played “Connect 4”, that’s the same game. If you want to watch some video clip from the web, “watch and listen”, OLPC’s media player, has you covered. Want some music? Use “tamtam”. This application is similar to Garageband, but not quite the same. Last but not least is “Record”. On the B2, “record” just took pictures with an okay camera. On the B4, you can take pictures with a pretty good camera AND record video with no time limit (as far as I can tell). I was surprised and overjoyed to discover I could take video with the new one.

One of the coolest applications is called simply “Chat”. It is basically an IM-ish kind of thing that works between all OLPC laptops. Since I got two laptops from OLPC, I could test out the chat application with my friends and family. I spent a lot of time having silent conversations with the friend sitting across the room, so that was fun. Etoys is another cool application, and it is definitely the program of a genius technologist. Although it is difficult to understand and use, once you get into the swing of things, it’s awesome. To use Etoys you make a “sketch” on the computer, then save it, and that’s where the fun begins. You can write “scripts” that make the sketch move around the screen in the way that you want. You can put it in “books” that have multiple pages for a flip book or make animations with it (ie. a bouncing ball, flying bird, eating kid, etc.). In Turtle Art, you get a chance to write a simple program that makes the turtle in the middle of the screen move. It’s very cool.

Last review, I said that my main problem with the computer was its slow speed and its battery charge. And I am happy to say that both of those problems have been fixed in the new version. It has more applications, higher quality camera, more games, a few design changes for the better, and much more. I tested how long it would stay alive by opening it and leaving it open. Surprisingly, it stayed awake for more than four hours! And some other testing revealed that the B4 does, in fact, auto save your documents and stuff if it runs out of battery while an unsaved document is on it. I like that feature, because there were many times with the B2 that I was typing and it just died, leaving me rather stunned for a couple seconds until I came to my senses and wearily plugged it in. Then it would take hours to charge up again. But in the B4, it charges up really quickly. Another minor turn for the better is the plug. Now they are greener, more round, easier to hold, and they have the XO sign on them.

I thought that this version was way better than the last one. It was just easier to figure out, more fun to spend time on, just better. It’s going to be hard to send it back to OLPC, but I’m going to have to. It’s great that they’re going to start selling them to the public. (You have to buy two, and you send one to a needy kid in a third world country and keep one for yourself. Read about it in the New York Times… …) I hope I can get one!

For a regular laptop, this would be the paragraph about its problems, its deficiencies. But the thing is, there aren’t any problems with this computer! Congratulations, OLPC. You’ve done it. Or will you come out with yet better laptops? Is that even possible? We’ll have to see…

[I recently got my hands on one of the One Laptop Per Child machines. I found the perfect person to review the machine. Today’s guest blogger, SG, is twelve years old and is the child of a close friend. I lent the laptop to SG and asked SG to write a review, which appears here just as SG wrote it, without any editing. –Ed]

I’ve spent all of my life around computers and laptops. I’m only 12 years old though, so I’m not about to go off and start programming a computer to do my homework for me or anything. My parents use computers a lot, so I know about HTML and mother boards and stuff, but still I’m not exactly what you would call an expert. I just use the computer for essays, surfing the web, etc.

Over the last few days, I spent a lot of time on this laptop. I went on the program for typing documents, took silly pictures with the camera, went on the web, played the matching game, recorded my voice on the music-making application, and longed for someone to join me on the laptop-to-laptop messaging system. Here is what I discovered about the OLPC laptops:

My expectations for this computer were, I must admit, not very high. But it completely took me by surprise. It was cleverly designed, imaginative, straightforward, easy to understand (I was given no instructions on how to use it. It was just, “Here. Figure it out yourself.”), useful and simple, entertaining, dependable, really a “stick to the basics” kind of computer. It’s the perfect laptop for the job. Great for first time users, it sets the mood by offering a bunch of entertaining and easy games and a camera. It also has an application that allows you to type things. The space is a little limited, but the actual thing was great. It doesn’t have one of those impossible-to-read fonts but it was still nice. When the so-so connection allows you to get on, the internet is one of the best features of the whole computer. With a clever and space-saving toolbar, it is compact, well designed, accessible, and fast.

But, unfortunately, the internet is the only fast element of the computer. My main problem with this laptop is how very slow it is. It’s true that I am used to faster computers, but that’s not the problem. It’s just really slow. I had to wait two minutes to get onto one application. That’s just a little longer than I can accept. Also, it got slower and slower and slower the longer I went without rebooting it. I had to reboot it all the time. We’re talking once every two or three hours of use! And one of the most frustrating things about the system was that it gave no warning when it was out of power (as it was often because it lost charge very quickly) but just shut down. It doesn’t matter if you’re working on your autobiography and you had gotten all the way to the day before yesterday and forgotten to save it, it just shuts off and devours the whole thing.

This laptop is definitely designed for harsh conditions. Covered in a green and white hard plastic casing, it is designed not to break if dropped. It has a very nice handle for easy transportation and two antennas in plastic that can be easily put up. Once you open it, you see the screen (pretty high resolution) and my favorite part of the computer: the keyboard. It’s green rubber so that dust and water won’t get in under the keys, and this makes the keyboard an awesome thing to type on. Every time you hit a key, it provides a certain amount of satisfaction of how squishy and effortless it is. I just can’t get over that keyboard. There is also a button that changes the brightness of the screen. The other cool thing is that the screen is on a swiveling base, so you can turn it backwards then close it. This makes the laptop into just a screen with a handle.

All in all, this laptop is great for its price, its job, and its value. It is almost perfect. Just speed it up, give it a little more battery charge hold, and you have yourself the perfect laptop. I’m sure kids around the world will really love, enjoy, and cherish these laptops. They will be so useful. This program is truly amazing.
