I had an iPhone 3G for the past two years. Upgrading to the iPhone 4 was as simple as plugging in the cable.
I need it for a business tool, to interface with calendar, task list, and addresses, as well as email and internet. It also serves some personal functions - photos, etc. I miss being able to read books on the device, which I could do with my tungsten, but there is no ereader app for the Centro, as I discovered to my dismay.
I use my iPhone as a business tool... and an iPod... and a GPS device... and address book... and calendar and tasks (all sync'd through Mobileme)... and ebook reader... and game device... and photos... and videos... and more.
I haven't personally tried the Droid--partially because I didn't want to start over again (remember, I only had to plug in a cable) but my iPhone is easy and does everything I need it to do. Never had a problem in 2+ years of ownership.
Thank you for the insight. Somehow, I dont think transitioning from a disconinued Palm product, which didn’t last two years on the market, will be particularly seamless.
I’m not sure which device I’ll get. Maybe I’ll wait till some of the furor dies down, and iPhone 4’s are more readily available. Is it that much better than your 3g?
