So my impressions after a good solid 13 hour session on and off...
Hardware: Alot smaller than I was expecting actually, the concave sides really give the impression of a compact machine. Looks pretty good overall, but the controllers are designed to perfection.
Dashboard: Is there anything MS haven't thought of? Well, actually yes, it'd be nice if you could download Marketplace stuff in the background, but aside from that, there's so much to see and try out - mostly for free. Options galore. Streaming from PC works great. HD trailers are great. Guide blade that is ever present works really well, and can be called up any time except in back compat mode.
Games: PGR3 - what can I say - stunning. Such a leap forward, the detail if you look is incredible, and it just feels so right to drive.
CoD2 - blown away again; a real cinematic experience and so intense.
PDZ - not got me yet, I'm having trouble getting into it. Can't seem to progress really.
Condemned - maybe the biggest surprise for me, I'm really enjoying it, even more than I thought I might, and the visuals and audio are outstanding, really adds to the atmos.
Live Arcade - played a few, the mrs loves the idea of this.
Back compat - played a few flawless games of Pro Evo 5, online and off. Slight improvement in gfx, but not so you'd notice really.
All in all, I'm even more impressed than I hoped I would be as it all works so well together, though the naysayers had me doubting for a while. How anyone can claim this isn't a massive leap forward from Xbox is beyond me - see it in proper 720p on a 32" screen or up, and it's gorgeous. Not really been online much yet, so that comes tomorrow!
