I don't understand the idea that, given the opportunity, one would willingly put less power into a computer.
I've been using a Droid Incredible for 2 years. It was released 1.5 years before that. It handles all of my mobile computing needs just fine, CM7.2 is sturdy as hell (just passed 30 days uptime) and I haven't spent money on mobile hardware for 2 years.
I've gone wifi-only since buying this phone. I have wifi everywhere I need it except grocery store checkout lines. The phone lasts 2 days on a charge in perpetual airplane mode too.
the definition of "enough" will change in 2013
