You sound like a paid astroturfer except that instead of posting on Engadget you are posting on a Mac-centered website. Maybe you earn twice as much doing that.
As for Xbox Live, wow, that's great [sarcasm]...it's so awesome of an experience to have to listen to 10 year olds cuss at each other trying to act like they are older. That exceptional service was old and tired around the time of the release of Halo 2 on the original Xbox that Microsoft opted to prematurely kill off. They abandoned their owners, and as an owner of the original Xbox, when they did that, I chose to abandon them and move up to the superior PS3. Did Sony abandon the PS2 user base? Nope...they are still making PS2s and companies are still releasing titles for it. Microsoft could learn a thing or two about how they support their non-Windows clientele. Sony commits to 10 year life spans for their game systems, whether it is the PS2, PSP, or PS3. Likewise, Apple supports their owners for a long time. Case in point... my parents' eMac from 2003 can run Leopard, but how many low to mid-range PCs from 2003 can run Vista?
Netflix being available on the Xbox 360 is not a selling point. The Xbox 360 is supposed to be about HD, and NetFlix's online streaming is not HD or pseudo HD. I know because I'm a NetFlix subscriber and I'd rather wait for the Blu-Ray discs to arrive via the mail so I can enjoy a real 1080p HD experience. If I wanted to settle for non-HD streaming movies on my non-Apple hardware, I'd use my TiVo and Amazon Unbox.
Regardless, all of those *amazing* features you speak of in terms of the Xbox 360 are hard to take advantage of when you are having to ship your broken Xbox 360 back to Microsoft to replace all the time. I've had my PS3 for a year and a half and it's never given me any problems. But then again, Sony costs more. There's an old adage about "you get what you pay for".
