The Blackberry 8100 has the looks and dimensions to really tempt me.

Update:
RIM Officially Announces Blackberry Pearl (8100)

There is actually still no official announcement from RIM or T-Mobile about the 8100, but tons of information has already leaked about this new slick The Blackberry. Engadget Mobile has photos of the retail packaging and several photos and even videos showing the 8100 in action.
There are still no exact measurements of the 8100, but it looks very thin and compact. Known specifications include screen with 240 x 260 pixel resolution, 1.3MP camera, Bluetooth, microSD card slot, quad-band GSM and EDGE.
The release date for the Blackberry 8100 (aka Pearl) is supposed to be on September 18th or maybe already September 12th.
The Blackberry 8100 leaked first time early August.
