First, some context: Madonna (yeah, her) compared McCain to Hitler. Thus this response:

The Obama camp thinks ridiculing John McCain for not being wired enough will win him votes. Hmm.

Consider this, from Jacob Weisberg wrote in Slate in 2000 — eight years ago

Six months ago, no one would have pegged McCain as the most cybersavvy
of this year’s crop of candidates. At 63, he is the oldest of the bunch and because of his war injuries, he is limited in his ability to wield a keyboard.

But McCain’s job as chairman of the Senate commerce committee forced him to learn about the Internet early on, and young Web entrepreneurs such as Jerry Yang and Jeff Bezos fascinate him. Well before he announced his exploratory committee, McCain had assimilated the notion that the Web could be vital to the kind of insurgent, anti-establishment campaign he wanted to run.

…Last night [remember folks, this was 8 years ago] McCain participated in another Web first: the first-ever “cyberfundraiser.” At the event, he boasted about the latest returns from his Web site. In the first eight days following the New Hampshire primary, he raised $2.6 million on the Internet, for a Web total of $4.1 million from 40,000 individual donors. According to Fose, money is still coming in from the candidate’s Web site at the rate of about $100,000 a day. In addition, the Web site has had 10 million hits in the week following New Hampshire. Some 100,000 people have clicked a button asking for volunteers who want to be actively involved with McCain’s campaign. One of them was Andy Grove, the chairman of Intel.

So Obama is throwing rocks at McCain for not using email, while proving his campaign can’t or won’t use Google.
