The standard MotoQ's battery life is a severe limitation for heavy email users. I switched from a 700w to the Q about 2 months ago and miss the extra functionality that PocketPC offers over Smartphone. If I forget to charge my Q overnight, I'm without power the following day.

While the portability of the Q is nice, I find myself frustrated by not being able to copy and paste text from emails to websites or contact info and use MS office documents as 'natively' as I did on my 700w.

The 700w had it's shortcomings as well, anemic RAM being the foremost, but now that Sprint released the 700wx with double the RAM, I think that device should meet my power user needs. Rumor has it that Verizon (if you're beholden to that carrier) will release the 700wx in Q1 07.
