No doubt MS's tactics during the height of the v4 browser wars were low, but...
A web browser is an integral part of the operating system of any modern user-based computer.
Sure, ship Windows without IE. Ship it without any browser, or for that matter http tool. The Microsoft implementation of the ftp command line tool should probably be removed too.
IE bites, but a browser *is* an integral part of an operating system. (I won't buy a cell phone without one!)
I just wish anti-virus was too.
