Disclaimer:
Bose is obviously in a very interesting position in the audio market. They've never followed major audio trends (but the one constant always been accuracy, and they aren't into that either).
However, they are a very good business. They market their speakers against home theater in a boxes against import giants like Sony, Yamaha, Onkyo, etc.
These companies used to actually lead the world in audio design, but partly thanks to the collapse of the world monetary system in the 70s, where the US demanded currency depreciation against the rest of the world so it could be more competitive in the world market (or it would impose massive trade barriers), every other country had to appreciate its currency (hurting US importers). This is part of the reason why the Japanese import giants mostly sell cheap stuff here nowadays, but you'd never see these products in Japan.
On to the more important point, which is these companies dominate the low end, and with the long standing market penetration, everyone (under the age of 50 anyway, who had a clue at some point) thinks these are "normal" for speakers, rather than bookshelves and floorstanders which dominated loudspeakers until the 1980s. Bose today simply sells a slightly better product, and at a marked up price. Comparing the two makes it easy to see Bose is better. Bose is in this position because they achieved market penetration back in the 70s, when they actually had an audio mantra (stereo everwhere) rather than just selling a priced-up "me too" product.
Have I heard Bose? Yeah. Have I owned Bose? Yeah, but only the low end 2.1 Mediamate speakers, and those (as I look back to my foolish days) were horribly overpriced, but had the Bose name.
Do they "suck?" That's a value judgement. Some people buy it for decor (I believe it's called Wife Acceptance Factor). Some buy it because they heard its good, from a friend, on Time magazine, or the Shopping Network. If you are happy with it, your say is the last. If you are trying to achieve audio nirvana, well, I *IMO* think you could do better for the same money or even a lot less.
