A couple of weeks ago, I moved my mobile life back to a Blackberry Bold 9700 from T-Mobile after being on a Dash 3G for the last 6 months.
It's like breathing air again.
Admittedly, I am not the typical modern smartphone user. I prefer a full keyboard over a touchscreen, and I still operate in a mainly text-based world. So the Blackberry is exactly what I need to get through my day. I get my work email fast, the GMail app is fantastic, and UMA is really an astounding thing.
When you compare the Bold 9700 to its predecessor in my life, it is like moving from a broken Windows 3.11 486DX to a new MacBook Pro. WinMo 6.5 is not a modern mobile platform and on the Dash 3G, it only gets worse.
It's not T-Mobile's fault that they have the Dash 3G. But I am glad it's not with me anymore.
