Okay, the Mac-PC ads were funny at first. They didn't start out as attack ads. At first Mac poked gentle fun at PC for thinking that his graphic add-ons were easy to use. The message was that PCs are designed for business purposes but that Macs are better for home use. Very congenial, ha ha, very nice.
The last few weeks the tone has changed. Now Apple is running full-bore attack ads against PCs. They're nasty and unpleasant and inaccurate. (I say the latter as a current Vista user and a former user of Mac. I didn't expect to like Vista but I do - very much. The Allow/Deny dialogs are not a problem, and except for a minor bug in the email import wizard, I haven't had any problems with it.)
It's too bad Apple didn't quit while they were ahead. They had a really good thing going, and they blew it. They started out looking like the cool company, and now they just look like another bunch of big business jerks.
