Interesting. The problem with Xbox is that every time I turn mine on, it has to do an update. By the time it's done updating, I've forgotten why I turned it on. It is also louder than many commercial aircraft, drowning out whatever you might be doing on it.
So for TV, I just use a tiny computer under my TV, which can download stuff from Usenet and play it without requiring updates or nine billion cubic feet of air per minute.
The original Xbox 360s were incredibly noisy; the recent slim-factor models are much quieter—especially when running games off the HDD.
Updates, though, are very infrequent—I'd guesstimate about one every four months (although individual game updates can be much more frequent).
It's interesting you mention using a computer instead. The reason I like game consoles for gaming so much more is that they remove all the hassle of configuration and hardware issues—you just put the disc in and play. It looks like this'll be the case with TV as well.
I can't tell if you're just randomly anti-MS trolling here or if you're confusing a 360 with a PS3? Because PSN updates all the damn time, and Xbox 360 dashboard updates no more than every 6 months.
