There are lots of NMTs today there are reasons to keep one. Previously I owned WDTV1 now HDPro. I was tempted to get xtreamer and wdtv live when they released recently but I realized that I only wanted the following that decided to stick with my HDPro :
1. Has internal 3.5 hard disk and can handle my 1.5 TB
2. Control buttons in the unit. You can still use it in case of remote malfunction or you lost most NMTs has no control button.
3. Good Picture Quality And zooming functions that PQ will not suffer
4. DTS Down mix
5. Fast loading
6. Can play most of my mkv movies
7. Can read iso with menu options
8. Can connect to network & dowload torrents
9. Affordable price
10.Technical assistance (from spike) and firmware support
Im not particular to GUI and other juke box features what is important for me is I canwatched and finished the movies without any problems. Maybe you can share yours
