With the Storm, you certainly get a lot of functionality that Apple either ignored or decided we weren't ready for some functions and copy/paste most notably. Windows Mobile devices have included most of the capabilities of the Storm for a long while, but minus the tremendous connectedness of a Blackberry. Going from a WinMo phone to a Storm is pretty simple once you learn that it's a different universe and get the hang of the tools. I have a single friend with a G1, so I can't be too specific about how it measures up I have used it for about 15 minutes and it feels good, but I much prefer the size and feel of the Storm.
