I have both phones (I have a Sprint TP ported to verizon service & a 6800 with nueROM3) & I think I can give a fairly unbiased opinion because I still love my old xv6800 (Titan/Mogul) Running nue3 with the POS camera disabled, I think the 6800 is a killer phone & I really miss some of the features of it when I use my TouchPro.
The battery life in the TP is atrocious. I have four batteries, two cradles & a car charger. I never use the hardware KB as I got used to using Touchpal & never looked back (in portrait mode using T+ I can type insanely fast in sms-chat). As far as the hardware KB's go, I think the TP KB sucks -the keys are way too small & stiff
IMHO.
The virtually unlimited free memory in the TP is awfully addicting, I run Oxios 10 times a day in the 6800. I badly miss the scroll wheel & dedicated hardware keys for inet & messaging. TF3D & AEbutton + makes up for some of that, but I would love to at least have my scroll wheel back in the TP.
To all you guys claiming the TP is slow/laggy etc, that maybe true of the demo your playing with in the store, but I can tell you with a few tweaks that is not the case at all. My TP is lightning fast & I get no lag whatever in TF3D witth the speed tweaks & mine is fairly well customized:
I run weather panel from a 2nd today screen mapped to the right soft key.
I think the "new improved camera" is a useless POS. The auto-focus shutter lag is worse than a 10 year old digital camera. It works fine for inanimate objects, but forget trying to photograph your 8 year old daughter or your dog. If you look at the posted shots, 85% of them are dark blurry grainy out of focus shots & it's not really the users fault most of the time.
The TP screen resolution is killer, but I really want a bigger screen. If I can ever get my hands on a Pro HD I would buy it in a heartbeat. Sling Mobile has never seemed to work as well in the TP as it did in my 6800, although I can hook the video out to my 7" NAV screen in my truck & show the Sling video on the NAV screen (that is VERY cool)
I have had no overheating problems whatever with my TP even when running sling & GPS at the same time.
I can't get s2u2 to work correctly in the TP, but PocketShield while not free works perfectly & has some very cool features.
If anybody has any questions (I'm sure I'm forgetting some stuff), post here or PM me & I will try to give a fair unbiased answer.
