I'm in the market for a smartphone, but not sure what to choose as a Mac user. It seems that all the new models are on the PocketPC platform, and the only alternative is to get a Treo or SonyEricsson P910, which have both been out for almost a year. I would definitely prefer the Palm platform because I have purchased a lot of existing Palm software. But I would also consider Symbian, Blackberry, Linux if necessary. Are there any upcoming releases to look forward to?
