I have a non-rooted Inc and still over 200 megs free for apps, but two apps I try to udpate failed and then would not reinstall. Magic Gem (paid version) and Paper Wars both failed to update and now will not install at all. This is the first time I have had the problem and this includes a rooted G1 and using the market since the G1 launch. Both apps did this within a day, but other apps appear to be fine. I have emailed the devs, but zero replies.
