So what's new?  A LOT.  This version is heavily optimized for current and future-generation portable music players.  Today over 60 devices work with WM Player 10 tech beta, with more on the way.  Napster and CinemaNow are also incorporated into the Digital Music Mall, with more on the way - more choice of services to fit different lifestyles and budgets.  Some of us prefer monthly all you can eat, others prefer per-track downloads. Subscription/purchased music and movies are first-class citizens, easily discoverable and transferable to portable devices that support the new MTP technology (Multimedia Transport Protocol).  If your device doesn't support it today, contact the manufacturer and tell them you want it. 

Speaking of which, Auto Sync is in here too, an awesome addition for device users- dock your device, sync it.  Pull it out, transfer stops, plug it back in, picks up where you left off.  You can even customize which content syncs based on priority-based artists, genres, playlists, auto playlists or just sync it all.

You'll also notice that sync is multi-tasking- previous players converted, then transferred songs.  Now it's all on the fly- faster and easier.

Of course, Portable Media Center devices will do even more with sync, including syncing of your photo libraries to PMC devices and Recorded TV when they hit the market later this year. 

Speaking of recorded TV, programs recorded with Windows XP Media Center Edition also show up in the new player library.  Personally, I like to record programs, dump them to my laptop for watching on the plane- media player 10 makes finding and organizing my shows a lot easier.

As for the sleek new chrome, it's not all fancy polish either.  The dev team heard you LOUD and clear about making it easier to do common tasks such as on the fly playlist creation, burning, and transferring music without a bunch of extra tab-clicks. Not all of the UI work is in yet, but you can see where it's headed.

Library perf is also improved and will only get better- for those that provided your large libraries for testing- thanks and let us know how it's working vs. MP9 Series.

Note that the technical beta will only be made available in English language in order to focus our testing.  Final version will be available in all currently support WM Player languages.

So for the hard-core, check it out, let us know what you think in the newsgroups or here.  I'll start compiling a list of tips and tricks- send what you find my way too :)

Thanks for helping us test and make WM Player 10 the best release ever. More to come...
