They don't really have enough money - Comcast has a market cap of $60 BN. Jobs and Cook have been incredibly fiscally conservative - there's absolutely no way they'd try to acquire a company this large. If they were going to do this, I think the only way would be to buy a 10-20% stake in Comcast, get a board seat or two, and make it a "strategic partnership."
(That said, I don't think there's any way Apple wants to get anywhere near Comcast's awful customer service reputation.)
I doubt Apple would spend it all in one place, but it has more than $60 billion lying around just in cash reserves alone. Also, Apple has a market cap of $300 billion, that dwarfes Comcast's $60 billion.

It actually might not be that bad for Apple. There's no place to go but up in terms of Comcast's customer service, and Apple could always present it like it is a serious uphill battle (which it is), so if they don't kick its ass out of the gate, it'll just be one of those things Apple tried but couldn't do. Of course they'd still be left with this huge service albatross if it doesn't work out, and that's where the risk is.
AOL bought Time Warner. Google bought DoubleClick and Admob. Adobe bought Macromedia. Oracle bought Sun. AT&T bought Cingular. Anti-competitive acquisitions happen all the time.
