Is cm7's stable 7.0.3 market limited with apps? For some reason, the apps available on the marketplace for my nook is extremely limited. Am I doing something wrong? I have very few apps, and I only have 2 things to select. Top paid and Top Free, both with very few apps.

Your ROM's density value should be in the /system/build.prop file (look for an entry about "LCD density". It can be modified manually or with one of several apps.
