I'm considering the Cowon D3 after owning a J3 and an X7 and being a big fan of Android, but I've seen mixed reports of the D3's performance, some calling it downright sluggish. Judging by the video DFKT put online I wouldn't call it sluggish but there sure is room for improvement. Has anybody tried tweaking the player? I saw DFKT was using lots of widgets and thus wasting valuable RAM and CPU power... If I get one I would start with rooting it, getting Android Market on it and then install LauncherPro or one of the many other 3rd party launchers available. Most of them take up way less ressources than the stock launcher, so there should be some performance gained just by doing that.
Taking it one step further, you could install Titanium backup and start removing the system apps you don't need. I won't be using mine for mail, calendar, web surfing etc. so those apps could be tossed out right away. The same goes for all the clock widgets, games, "internet phone" etc. Am I the first to consider doing these things or has somebody tried it already? I just want a barebones platform for Poweramp and streaming music
