Ok so here is my take on the Pre.
Pros of the PRE vs TP:
1) The OS is MUCH better than WinMo (no comparison at all.) I have eventried the 6.1 roms and even the 6.5 roms. nothing comes colse to the responsiveness and smooth fluid transitions of the Pre
2) Web browsing is much better than the TP. Pages load faster and the zoom feature is cool.
3) Battery life is much better than the TP. (at least for me it is...I have tried battery and performance cabs, reg edits etc... but the Pres is more efficient
4) Instant email notifications. Syncs with my hotmail and gmail with no problems
5) Multitasking is very nice and easy to do.
6) Auto sync with my google calendar and it upates in real time.
7) Sprint TV is less poxelated and easieer to navigate through
Screen resolution is fantactic and vibrant
9) Slimmer more modern design (not a big issue really but slimmer and smaller is the trend these days)
10) Scrolling is smooth and very responsive
11) Contact menue is more user friendly and will auto update/correct any duplicate contacts etc.
12) Standard head phone jack
13) louder speaker phone and earpeice (no need for an audio boost app/cab)
14) Screen rotation is more responsive (TP would lag and sometimes never rotate or would rotate in wrong direction)
Cons of Pre vs TP:
1) Teathering is an option, but doesn't work (gets error that internet sharing isnt avaliable)
2) No TV out (never used it on TP, but still a limiting factor)
3) No removable storage (I only had an 8gb minisd anyways, but once again a limiting factor)
4) Limited apps for now (unless you get the emulator, but I saw a video of the emulator and I did not like it...seems like something was put together to make previous Palm users satisfied till full app support is avaliable)
5) Keyboard is ok but far inferior to the TP keyboard ( However I do think it is mor convient to slide down keyboard (or slide up the screen) instead of turning you phone sideways in order to use the keyboard)
6) No digital zoom (The pic quality is very nice but no zoom feature)
7) No video recording (heard that an update will fix that but we all know about those updates)
no external notification of a missed call or txt msg etc...(will have to turn on screen to see if you missed anything)
Overall I am satisfied with the Pre and do not regret getting it. Now I will put my TP phone up for sale on craigs list
Hope this post helps
