Yeah, I've found MC to be just as easy to use as MJ. It's just a matter of ignoring all of the things you don't want to use --- all the good stuff about MJ is till there, there are just a lot of other cool things as well. Plus, MC is very custimizable, so you can turn off a lot of the services you don't want, change parts of the display around, etc.... tailoring it to be the ultimate Jukebox, while retaining the power of MC's newer features. Uninstalling MJ and upgrading to the latest MC is worth tackling the learnign curve for, because in the end I tihnk you'll be much happier.
On the other hand, the one problem I have found between the Media Center versions and the old Media Jukebox versions is that with MC I experience more slow-downs -- sometimes tagging can be very slow, as MC freezes up for seconds or even minutes at a time if I've been doing a lot of file/tag alterations. Sometimes it's fast, and then sometimes I'll just try to update a single field of a single file, and there will be this long pause before I can actually make the edit.... MJ always had much faster response times, no matter what I was doing. But MC 11.1 is much improved in that regard compared to MC 10. Still slows down more often than I'd like, but it has improved. And to be fair, I should admit that I've got a much larger database of music and video files now than back when I was using MJ -- so that could be a big part of why things are slower for me now. (If I had more RAM and a faster processor I'm pretty sure MC 11 would run like a dream.)
But you'll find the tagging ability, plug-ins, cover-finder, tag cleaner, CD Burn and Rip, etc., are all better with MC than MJ. And the podcast support in MC 11.1 is very convenient. I could go on and on... MJ is a great little program in it's own right, though, so I can't knock it. Simpler days...
