They all do many of the same things. Honestly, it comes down to what features you want on your phone and the learning curve you are willing to deal with. One of the advantages of the iPhone is that it is ridiculously simple to learn to use—especially since so many people already have an iPod or have had one, so they aren’t starting from scratch. I believe Palms still exist (my friend has a PalmPilot phone) and they have another system all together. I would say figure out what you want your phone to do. Go to the store. Tell them your list, then make them tell you what phones will work for you. Especially include things you want your phone NOT to do. I’m so ready to be called out on this: Business folks tend to get Blackberries, because they’ve been around the longest and are easiest to work with as a business when it comes to getting your e-mail sent to your phone. They also have permanent keyboards which lots of business folks like. Kids, people who want the “next new thing”, Apple crazies, and the like get the iPhone. You should feel free to read that as “yuppies”. Does not have a permanent keyboard. I have one. Sidekicks tend to be used by youths in less affluent areas. There’s a great editorial somewhere that I can’t find right now that is about how Sidekicks are the best phones ever and it makes some pretty interesting claims about why the rest of us don’t use it. Annnnd Android is still new enough and came out, honestly, at just the wrong time to not really have a “type” yet. Had it come out a few months earlier, I might have waited on getting the iPhone to see which was better. Anyway, it’s by Google like you said, but I haven’t had a chance to see/use it.
