Tossing a computer in your pocket is perhaps a little difficult, unless you have a UMPC. In fact, Sony has just unveiled on of the cutest little Ultra-Mobile PC's I have ever seen.

Thus little computer is an extension of the Vaio UX ultra-mobile PC line. What makes it unique is the fact that it has no hard drive. Instead, it uses Flash-based memory. Of course, it takes a hit storage wise. The original HDD based versions have some 30GB of capacity, whilst the flash-based units only come with 16GB. Here's a few more specs.

• 512MB 400MHz DDR SDRAM
• 1.06GHz Core Solo U1300 or 1.06GHz Celeron M 423 processor
• 16GB Flash Drive
• 802.11a/b/g
• Bluetooth 2.0
• 4.5 inch SVGA 1204x600 touch-screen display
• Intel 945GMS integrated chipset
• 5.91" wide x 3.74" tall x 1.50" deep
• Windows XP Home or Pro versions available

The new Flash-based UX models do weigh in a little lighter than their HDD based predecessors. The Flash models are about 492 grams, while that old hard drive kicks it up to 502 grams. Thankfully, the price tag is the same at around $1800 USD or just over $2000 Canadian dollars.

One unique aspect of the new Flash-based models is load times. Apparently, Microsoft Outlook would take up to 9 seconds to load on the old HDD based models, but will fire up in only 1.5 seconds  when running off the Flash-drive. This new UMPC is Sony's attempt to compete with Samsung, as they already offer their Q1 UMPC.
