My comments? Okay, well,

The basic experience is great. I love turning the machine on and off from the controller, and that they turn each other off.  The 360 will turn off the power in the wireless controllers when it shuts off.  Very cool.

The ability to download demos, trailers and XBox Live Arcade stuff really rocks. Being able to be in control from the controller at all times is awesome too. I can exit any game and get back into the market, lanuch another game or shut it of from the controller. It's great!

My only current suggestion, which is probably obvious, I think the XBox Live Market should use a more html/flash like interface so you can update it constantly with interesting content to point out what's new, hot, cool. As it is it's pretty bland and the only way to find out about stuff is generally to read about it on the PC or through a friend but not directly from my 360.

As an example Rhapsody does a pretty good job of showing me new stuff everytime I log in. They have one window that shows their top 5 promotions (rotating) and they have the most popular list as well showing what's hot as well as a few other things. All of this gives me something to look forward to when I log in.  I'm sure you guys already have plans for something like that.  I supposed another suggestion you might already be doing is you might need 2 interfaces. One for HD and one for old school TV similar the XBMC.  On a TV you can't display as much info as Rhapsody does on a PC but on an HDTV you could certainly get closer.

Oh, one more, Windows Media Connect sucks ass. Everytime it starts it has to scan all the media. I've only got a moderately sized collection of music, maybe 8gig and it takes it like 20~30 minutes to scan through it meaning I can't access any of it until it's finished.  And worse, it takes 35meg of memory and slows down my PC since for the first 20~30 minutes it's constantly accessing the HD to scan all my mp3s   That's very not cool which means I enjoy my 360 less, especially when playing games that were arguably designed for you to play your own music (Uno, Gravity Wars, etc...)

Over all very cool though. The other 2 consoles have lots of catching up to do I think. I'm very curious about Wii's "always on feature". Thinking about that it seems like both PS3 and 360 could have benefitted from a little more brainstorming before they finalized their hardware.

True, I don't think Nintendo is expecting to download large amounts of data on Wii. I think they were thinking more like Animal Crossing DS and Nintendogs where while you are not playing things can still happen. Of course arguably that's pointless since you could achieve the same thing the moment you turn the machine on by checking some central server to see if someone sent you something.

To be honest, none of the machines really seem to be designed for media centers (I assume that's what you mean by big content). 20gig? 60gig? not even close. An iPod has 60gig and that's just for someone's music. Where does HD video fit unless the big 3 expect people to delete everything? Hopefully if both systems ever do a good job of being a media center someone will figure out how to connect a $80 300gig HD (current prices) of course given they both hobbled themselves with small HDs they're going to have a hard time becoming media hubs.

Oh, by the way, I saw a 360 running on WMC. Very neat idea but again poor implementation. The friend had probably 20000 songs. Trying to scroll to John Coltrane literally took like 2 minutes

You are kind of screwed. My understanding is you have 3 options

#1) US 360. Will only play US games

#2) Japan 360. Will play Japanese games and Asian games but not US games

#3) Asian 360. Will play Asian games only

There are exceptions since it's up to each company to decide if they want their game to be region locked or region free.

You can generally order the asian version of games pretty reasonablly from http://www.play-asia.com. They are the English version with a Chinese insert so you don't have to worry about language issues and they will run on a Japanese 360.

Basically I would say get a Japanese 360 and then just realize that you'll basically need to buy another one when you go back to the USA.

I just bought a 360 here in Japan because:

a) the setup screen lets you choose English as the system language.

b) Silver account can be set as your home country

c) I got a free 1 month gold account... not sure what happens after that with regards billing.

d) www.play-asia.com has tons of region free (ie play on any xbox 360) or ASIAN region (inc. Japan) games for 40 dollars each... that's a good buy in my book, especially with free shipping.

e) UK TVs will play NTSC as an output, only trouble is the voltage...

--- However, Greg is right. WMC is hopeless. First it takes forever to scan all the music every single time... what's up with that? Second, it sees other folder shares with the dashboard music player. Try going into Media Center, it sees my MCE laptop, but will only look in the My Music folder for music... unless I am doing something seriously wrong!
