You can now pre-order the new HP TouchPad (which isn't actually listed as the TouchPad 4G) at Amazon for the low, low (read: high, high) price of 700 bones.
The TouchPad 4G is going to offer some improvements over the original, most significantly, 4G. It's set to go on AT&T's HSPA+ (and signing up for a AT&T data contract will almost certainly knock a good chunk off that steep price), which should give it a nice speed boost. Other enhancements? It's going to bump the original TouchPad's processor up from 1.2GHz to 1.5GHz
(still no dual-core? Really?), (that IS a dual-core. Never write before coffee.). It'll also launch with version 3.0.2 of WebOS. Hopefully those three factors will give it a much-needed speed-boost.
