Well ICS does pave the way for that, a standardised Android version that works on all Android devices be they tablets or phones or phonelets!
The Market is improving every other month with new awesome games, new apps and each time they look better and more pro as better devs join the force.
It is improving, indeed, but the Apple app store is still improving too. I can't see the gap being closed for a long time yet.
Obviously if you don't care about games and/or the apps that you want are already on Android, it's not really an issue. You can also use the superior browser support in place of an app, but the apps always work better!
