I'm one of the one's who can't deal with the current closed nature of the iPhone platform, but I'm looking for a smartphone. I don't really want to deal with Windows Mobile either, so that leaves 3 things as far as I can tell, Symbian/S60, PalmOS, and Blackberry, and Blackberry seems to be really light on the stuff I'd want to do. PalmOS is obviously dated and starving for developer attention, but it has lots of apps already, surely enough to satisfy me, not to mention it's snappy on modern devices. I have no experience with S60, but it's apparently at least as modern as the iPhone under the hood, and it seems to have a good application base too, though I'm having trouble finding freeware for everything I'd want. Is it worth getting a Centro or a Palm-based Treo, or should I look into S60? Anyone used both and have experiences to share? And as an aside what draws people to Blackberry? Thanks in advance..
