of course that only matters if op plans on playing games. otherwise, the higher resolution is just fine in everything else
Not just games.
My friend's bank has an Android app that literally doesn't work on higher res screens. The interface is unusable. He has to use the Honeycomb "Zoom" mode to make it work, which looks terrible.
You never know what apps are going to fly to pieces (or just plain look terrible) at high res on Android until you have a high-res screen. Personally after over six months with my Nook Color I had a pile of applications that I have bought that I was waiting to try on the SGS2 because they broke on resolutions higher than WVGA.
The higher resolution isn't the only issue- onscreen buttons are also a compatibility issue. Some applications just DO NOT like Honeycomb's navigation bar that can't be hidden. They crash or act unstable, waiting to be re-written for such compatibility.
The real issue is that Android is the second platform for too many Android developers- iOS is first. So when new challenges come in Androidland, they drag their feet reworking things to be compatible. Who wants to really bust their buns for a port on an OS that brings you less money?
Even worse is the fact that iOS made it easy for developers when it when high res- everything doubled. WVGA vs 720p is a completely different aspect ratio, so developers that are almost too lazy to develop for Android anyway now have to redo the
art in their applications for a new aspect ratio to work well. I just don't see that happening for months if not longer.
The Galaxy Nexus is a great phone if you are a developer, or if you only change your phones once every three years and you want something that is still relevant in three years. For the rest of us by the time we can get an upgrade again after the SGS2, the applications (and SOCs) will have caught up to 720p. We jump from the best of Android's old style phones to the best of the next style.
