I had a Sprint Hero for about a month (little less) and then a Moto Droid for the same time. When I got the N1 yesterday and I signed in with my gmail account and it said it was synching my info and I thought that was my email and contacts but it also installed all of the apps I had installed on my Droid and it even put the background picture for wallpaper which is not a standard wallpaper. Today I opened the Finance app and figured I would have to input my portfolio info but no all of my stocks are listed. I am extremely impressed. I dont feel the need for any backup apps.
