I would argue that there's nothing ground-breaking on Android phones either, but that doesn't stop me from loving my Evo.
I had custom ROMS, kernels, wireless/wired tethering, touchscreen controls, remote VNC, terminal, and thousands of apps/games on my Winmo 6700/6800. It simply lacked elegance, both soft and hard(LOL). Only when the iPhone innovated the finger-friendly UI (arguably, but you can't argue what brought the control style to the masses), did Google see the need to fill the vacuum MS left behind with its inability to forecast how phone UI was evolving, or even CHANGE AT ALL.
I haven't used Winmo7, just seen some demos, so I can't fairly judge it one way or the other, but if theres one thing I dislike it's being forced to use a format, even if I thoroughly endorse that format in the present. From what I've seen so far I wouldn't personally care for the overly simplistic nature of the "hub" setup MS is going for, but I know lots of people that would, if they can get their minds off of the iPhone's glittery, sparklyness.
