three free months of game time to anyone who is willing to switch from cable internet to "high speed Internet from AT&T," which I assume means DSL. Normally I wouldn't recommend DSL over cable, since it tends to be (much) slower, but if you use your connection mostly for WoW, email, and web type stuff anyway, it doesn't really matter. DSL does tend to be a bit cheaper.
There are a few caveats, of course. You need to be a new customer, and as far as I can tell, you need to keep your account open at least a month to get the reward, and there was something about a $75 modem charge, but there was also something about $125 cash back (the fine print is a little confusing). The offer is open until January 31, 2008, so you have a little while to make up your mind. If you've got cable but don't like it, free WoW is never a bad thing. Did anyone take advantage of the DirecTV offer from a few months ago? If so, how did it go?
