for me, ads are ok most of the time since i'm using most of the apps for just a very short period. This is due to the fact i don't use the Android for gaming purposes.
Nearly 95% of the apps i use and which i fetched from market are effeciency tools (Metal detector, gps-status, voice-recorder, and so on.) The other ones are free of adds. If they wouldn't free i think i would buy them if price is in range.
There is only one thing, if i really qould need an app and the price seems not to be in range, i simply would write this app myself, since i'm a developer
I published 1 app in the market since i got my G1 and pubished several nfty little tools here in on Androidpit, but none of my apps are payed apps. They're all free.
The way a developer chooses depend on what type of app he is publishing. A simple tool is only worth paying if it covers a really neccesary gap. Here it could be a good an veritable way for the developer to rely on a trial / payed version. If it is a game or something else i guess the add / paid way is the better. Depending on how good the product is.
