I think there would be more work done on apps if there was a truely open OS. The browser is the biggest issue - personally I'd rather not have flash (I have it turned off), java and microsoft's active whatever on my machine but I know many of you couldn't do without . I should look up what the "real" linux distros are using? I haven't tried minimo(sp? the ported browser app) but suspect it would do what I need .
Biggest problem is that they often need to be re-ported when Nokia changes their hardware or "upgrades" the firmware so why expend the effort when there isn't a "stable" platform to work with?
