The manual for the VMP75 is actually available on viewsonics website (http://www.viewsonic.com/assets/074/16403.pdf
) and reveals a few interesting features (many of which exist on other hardware, but not necessarily on the most reasonable competition based on Netflix streaming, the WDTV Live+ and Seagate FreeAgent Theater+).
1. BT downloading support.
2. Recording streaming video to HD (I'm not sure how useful this would be, but interesting none the less).
3. Using the remote to jump to a certain percentage point in a video (no more FF'ing through 45 minutes if you accidentally "Cancel Resume" on a movie).
4. Info button provides more file details (lacking in WDTVs)
5. The user interface isn't gorgeous, but it looks like the interface combined with the remote makes for easier navigation - for example, you can use media hot keys to jump between Video and iMedia, and stay within the directories of each section when you switch.
6. Official support for USB keyboard\\mouse (the WDTV Live Plus works with a keyboard and mouse, but it's hit and miss - I've gotten mine to work two out of five times I tried to use it). Good for the built in web browser I suppose.
Some of the buttons are listed as "Reserved" and the manual notes functions will be added later through firmware (namely the use of the "Help" button on the remote). While the "Help" function isn't really important, hopefully they are reliable when it comes to providing quality firmware upgrades.
I'm still undecided between this and my recently purchased WDTV Live Plus (as made obvious by my thorough examination of the manual). Some of those functions (and a lot more) would be added to the WDTV Live Plus with release of b-rad's firmware, but I love the fully functional remote (I always hated the WDTV remote - I like having a button for turning on subtitles\\changing audio language\\etc).
