Best keyboard phone is the Epic 4g
That said, I also have a replenish and its ok..but I am not the main user of it so ::shrug::..
At the very least don't expect too much performance increase from replenish to transform ultra...The biggest problem the transform and the replenish have is some apps not being optimized for the resolution, other then that the processing power is around the LG Optimus - Evo 4G.
Replenish is the only phone that doesn't have the smartphone fee..its only a 4g fee for those with sero...for everyone else its a smartphone fee...
I mean define "very minimum"..what exactly does he do?
Overall if you plan to go with replenish, I would suggest you ebay it. Look at it this way your upgrade gives you 150$, you can ebay a Replenish for $100 or less. I mean you can probably buy an iphone, ebay it and cover the costs + buy yourself a Replenish + make profit...
