To add to what jmurder said...Android is a whole different animal. Essentially all the features you want are there, its just a matter of how much tweaking you want to do. For example.. I might be the only one who likes everything on one screen. I hate scrolling back and forth between screens to get to apps. I achieve this with
launcher pro (locking to one screen),
wave launcher to access additional apps without having to go to another screen.
My lock screen is disabled, my notification bar is hidden. I press the wake button and I'm right on my homescreen. I got an app protector in case someone wants to get nosey
