Hi konttori, First, let me say I have not tried UKMP yet, and probably won't unless it offers some major new function over the competition to satisfy my selfish needs. So, feel free to ignore my uninformed request. However, one thing that *would* swing me into your camp quickly would be gapless MP3 playback. Once you've experienced it on material where it makes a difference, the lack is seriously annoying. And therefore, the first app to land this feature on the N800 will really have something to crow about. If you're interested in considering this enhancement, feel free to let me know and I'll be happy to play tester. Thanks and good luck with your efforts!
