OMG anything below 6 is way to slow for a power user.
I love my 9000, but with just a few must have apps it got
way too slow. For regular phone use its fine.
I'm currently using a Flip 8220 for personal use (running a custom 4.6/5.0/6.0 hybrid) as well as an 8110 for business use -- I'm working on hybridizing them both. Using CrunchSMS, these are awesome phones! I'm working on making them better so that lower income people who still want access to a smartphone (or people of any income level on a budget) can still have a decent phone with a decent OS with decent specifications in terms of app compatibility!
