Asus was first on the scene with their Eee PC. It was only available with a 7" screen, sporting Linux. Soon there will be a 8.9" version as well as a 10" version, with the option for Windows XP.




I bought my 17" Vaio several years ago, and at the time had there been mini laptops like these I would definately have thought twice about my decision. Some of them can get over 5 hours of battery life, all while being small enough to fit into a womans purse, or a man's purse, a murse if you will.
They aren't powerhouses, but my Vaio was intended to be a desktop replacement when I purchased it, and some of these laptops half its size are rocking nearly the same processor speed. For portability, and ease of use, I can see alot more people buying these.
Will they take over the world? Well, the Eee PC had quite a bit of success using only Linux, and with the low entry price to these the modding community may also find them to be fun as well.
