To Pre or not to Pre? The answer is clear: To Pre! I'm outside of a Best Buy right now. Got first!
I don't know why people have their sights set on a TP2. Sure, it's got a slightly better screen than the TP, but nearly the same hardware. Software wise, it's still TF3D. Multitasking is much more eloquent in the Pre and from what I can tell, is much faster than anything anybody can cook up for the TP.
The Pre, as all Palms since the 650, maintains the snapiness and responsiveness that the PalmOS was known for (at least to me). To this day, I still haven't come across anything snappier than a Palm phone. I hate lag, very, very badly.
