Well, I have a Samsung Galaxy which has been good. Got a hold of a friend's iPhone and found it anything but easy compared to the Droid OS. Smaller screen, more searching through menus. Really couldn't see why anyone would pick that phone other than name recognition.
I never understood the appeal of smartphones until my carrier gave me a free Galaxy when my contract came up for renewal, but I was hooked on it after a day. Best free apps and websites:
Google Sky Map: Uses accelerometer and GPS, hold it over your head and all stars, planets and constellations are labelled, also has a search feature to home in on an object.
nextbus.com: Gives an ETA of buses enroute to the nearest stops, updated in real time, for transit services that track their vehicles with GPS. Works in most major cities.
http://www.nationalpost.com/m/todays-paper/index.html: Arguably the best newspaper in the world, all articles from the print edition are posted online six days per week. I find reading on my mobile device is a lot more comfortable than using my PC.
