Bose sucks monkey balls. When you buy a set of Bose speakers you are paying top dollar for top quality marketing. They advertise in every magazine out there and put billboards all over the place, and they design pretty equipment. But they suck balls compared to other similarly priced equipment. As in, they are not even playing in the same league.
Bravias are good. Great, even. But they're way overpriced. I notice that you didn't say, "I need a good flat panel and speaker system," but rather, "I need a Bravia and a Bose system." That screams, "I am a sucker for marketing." If you want the best TV on the market you want a Pioneer Kuro II (not sure if it's hit the shelves yet, but it's nearest competitor is the Pioneer Kuro). A nice Panasonic plasma will probably also give you a better picture than the Bravia. Aside from that Sharp and Samsung both make excellent LCD monitors. But if you're set on a Sony, at least you will be getting an excellent (if overpriced) picture. As for the speakers, you're just fixing to pay loads of money for absolute mediocrity. Bose has never made great speakers, but lately they've been getting worse and worse. You're buying nothing but a name.
