I'm kinda happy about how the market's being shaken up for once. I had regarded the whole PDA / Smartphone market with a certain amount of distaste and disinterest for quite some time. My old Viewsonic PDA died and I found I just wasn't using it for anything useful.. and then I ended up getting the Motorola Q because at least it had a decent web browser and keyboard so that I could text people instead of having to deal with my basic fear of telephones.
My rant: One can write all the GPL'd open-source whatever software that will do all kinds of rotten things to a Microsoft Windows Mobile 6 device that Microsoft doesn't intend for you to be able to do. But you can't do that with an iPhone.
When I was using an mbox-based mail system, every so often I would have a mail corruption bug where "something" would go wrong. My Outlook email box has gone funky in the past and not all of the data is stored in an especially well documented place either.
