It installed a different version of the market which killed appbrain and fast web install...the market that is on the NC lacks good browsing... Sometimes, I like to visit the market on my NC and just look around to see what is out there, but it always felt like I was only seeing a small portion of the marketplace, with no way to advance to page 2. Remember, I am new to Android so I haven't had months to know what is out there. Appbrain allows me to window shop as it were and explore deeper into the market than the market app does. Now of course, if I am sitting at my comp I don't use it much anymore since the new web market is up. Like I said, its a personal choice and I certainly hope it doesn't dissuade others from using it. I know that I am in a very small minority on this one. It is just that that ROM doesn't offer any benefits to me, as I am running 1.1 fully rooted without it.
