I'm fine and dandy with the humongus capibilities of the PC but to Xbox owners loading off the hard drive and not having the loud ass DVD drive spinning up all the time is a big perk as well as the hopefully shortend loading times. Care or not, it's a big deal to a lot of people who own the system.
I don't care what you do with your money but anyone buying a gaming system for a UI and not for games pretty much defeats the purpose of a console. If you're looking for a media center, even though the 360 is one of the best media extenders, you could probably find a laptop or build a pc that does the same thing.
I really don't care for the UI either, but as I posted before, they aren't doing away with the blade system, as seen in the picture, so I'm not too worried nor would I if it didn't. I don't use my Xbox for the dashboard, I use it to play games.
I'll give you the games point, but let me explain a bit more why I'm not particularly concerned with that for the moment.
As of right now theres 2 main games I was insanely interested in - Gears of War (1 not 2 cause I haven't played 1 yet), and Mass Effect, both of which hit on PC.
I'll also give you the xbox360 load from harddrive point if you've already got the system. If you didn't already have it though it just means it got up to par with that particular aspect of PC's
And yes I was looking for something to add to the media center, cause for the moment the PC I plan to use as one is a tad bit underpowered, although I can fix that with around $300-400 (price of a 360 or close to if memory serves). Just seemed easier to get a 360 if it'd do the same thing, but if it's going to get an ugly-as-sin interface (my opinion) and lose functionality on the Blade interface, I'll stick with either Linux or Windows and make that media center pc. Granted I hate both Linux and Windows appearance, but that's fixable with a few mouse clicks and some downloading of themes
I'm still holding off though, it ain't August yet, and maybe Microsoft'll either have a change of heart or at the VERY least keep the Blade interface intact and let users swap between the two by choice.
Just don't get the idea behind changing the entire look of a system after it's been out this long either though, maybe THATS why I'm so against the idea...
