Ultranote has a great article that compares the features and size of the OQO and Sony U ultra-portable computers. There are a lot of photos which drives home how small these two jewels are. The author also compares the two devices feature for feature which should be taken with a grain of salt as the two devices are pretty different. Anyone curious about either of these devices should not miss this article.
