Although the difference is about 14GB of less disk storage, its worth the production. Why? The comparison of the integrated 16GB flash memory of the UX micro PC and 30GB internal HDD of micro PC are indeed awesome. With the 16GB of flash memory in the UX micro PC, its speed performance is way too fast to be compared. For example opening up a Microsoft Outlook program is about 1.5 seconds which is 6 times the speed of the internal HDD UX micro PC that takes about 9 seconds.

Starting up the whole 16GB flash memory UX micro PC takes only 5.6 seconds which is 3 times faster than the other modes that take 17 seconds. By using a flash memory technology instead of a internal HDD it will give the battery a longer life by 13%. Probably some of you might say, increasing operation hours does not really benefit me. OK, then what about the hit impact improvement? Whenever you happen to drop your Sony UX micro PC, you won't need to worry about any data lose comparing to internal HDD. A slight hit will probably harm the whole hard disk if it is on operation.

Other models of the Sony UX micro PC weigh about 520 grams and I would say I'm very happy with this one as it only weighs 492 grams. Cutting down 28 grams is a big work for them. The newest models of VGN-UX90PS and VGN-UX90S boast 4.5 inch WSVGA display screen and 512MB of RAM. It has an operation time of 4 hours and 8 hours for a separated battery pack. The whole UX micro PC will be powered by either Core Solo U1400 (1.20GHz) or Core Solo U1300 (1.06GHz) processor which runs on Windows XP. This incoming models of the SONY VAIO type U will hit the street price of 209,800Yen which is about USD1,807, its on its way to USA and Europe soon.
