Focus Flash
Pros: Samoled+, FFC, sturdier construction (imo) , 1.5ghz processor
Cons: 8gb with no expandable memory , 3.7in vs 4 on the original Focus
Focus
Pros: 4in screen, expandable memory (limited by certain brands and class)
Cons: 1ghz processor (imo it still does daily tasks just fine without any hiccups) , 1.3v vs 1.4v, no FFC
These are the things that i can think of off the top of my head. Honestly, if the Flash was not limited by their internal storage and had at least a 4in screen I would jump on it in a heartbeat. The construction felt solid in the hands but coming from a 4in and downgrading to 3.7 is not an option for me.
