$550 and $650??? Seriously, apple makes nice stuff but I don't get the part where they charge double what everyone else does, and people just pay it. Apple marketing, the real reason behind the success of iWorld. You just ain't cool unless you have an iphone!
The evo kicks the crap out of these phones. Or if you are an apple fan, it's at least as good. And apple fan or not, it's half the price. Half! Bigger screen, more powerful, removable battery, expandable memory, 4G... I guess if you like apple products and don't get any 4G in your area, it might make sense. In that case though, it seems you might actually be better off on a postpaid carrier for these phones, given the high price of entry.
The special monthly discount for iphone users is total bs but that's how apple rolls. They are a bully. You follow their rules or you don't play at all. So backwards for a technology company.
