The only reason i'm (extremely) hesitant to adopt sony, is because they consistently fail to back the dominant media.
Sony's history:
-BETA (vs vhs)
-Minidisc (vs cd)
-ATRAC (vs Mp3, WMA, and even ogg for god's sakes)
-SACD (vs. DVD-audio)
-UMD (vs. DVD)
-DVD+R vs. DVD-R (-R is still consistenly chosen as the most compatable, and industry standard for distributable masters, despite the +R technology's newly developed booksetting techniques)
And NOW blu-ray (vs. HD-DVD) i gotta tell you, i'm honestly quite hesitant to buy a sony-backed medium. And "Well, blu-ray is bigger, and better" doesn't necessarily mean anything, either. Betamax had much higher resolution than VHS, and then there was superbeta on top of that even. Minidisc was much smaller than cd's, and each came in their own permanent caddies for prevention of scratches, etc. for the same $$ as a CD. ATRAC sounds better than mp3, and 1st generation WMA and OGG files, +R was built from the ground up with compatability in mind, even with the proper systems in place for hardware level mt. rainier error correction (potentially could have been leaps and bounds above -R)
And guess what? They ALL took a backseat to inferior technologies. And i think the major reason is the so/so build quality of sony electronics. I've owned 3 ps2's, one first generation one, that stopped reading cd's correctly, and eventually stopped reading anything, a 2nd one which got broken, not sony's fault, and now my 3rd, which is the newer slim model, which after only ~60 hours of useage over the last 18 months or so, skips any time there's a movie in a game, sometimes to the point of freezing completely, and sometimes refuses to load games at all until i've reset the machine 3-4 times.
Needless to say, i wont be buying a ps3 until more long-term useage durability feedback accumulates, because i don't feel like getting stuck with a bunch of expensive games, and a console that wont play them
