imagine the chaos of firefox being installed by default on all new dsl or cable installs. no doubt it will also cause problem with the integration of ie with xp and vista...
not to mention the ill feelings people have toward AT&T. they could at least not be so obnoxious and arrogant about their ambitions. do one of those stupid toolbar search things first. see how it works. THEN attempt a new browser.
I'm curious what you think the problems will be, and why those problems would stop AT&T from installing their browser as a default. You make some claim about integration problems with XP and Vista. Surely many people use Firefox, Opera, or other non-Microsoft browsers on those platforms. What show-stopping integration problems do you foresee that would stop AT&T from doing such a thing?
For what it's worth I don't use Windows. I don't know of the existence or absence of such problems. I'm not trying to bait you in to anything here. I'm honestly curious if you know of something that would make this a headache that isn't worthwhile for AT&T to try. It is not something I would put past them.
