So I'll be replacing my 2007 MBP once the 2012 ones come out and I'm going to get a new external while I'm at it since my current external HD is only 250GB and it will be pretty useless to have a external HD with less capacity than my new computer. I'm trying to figure out whether I should splurge and get a 2TB Time Capsule or if it makes more since to spend the same amount and get a 3TB Western Digital External. I realize that the major difference is the wireless connectivity - so while it would be nice for my computer to automatically connect to the time capsule and back up but I'm not sure it would be absolutely necessary. My cable box is its own wireless router, so unless the Time Capsule will be a better wireless router I don't really need it for that. Is there any other reason to get the Time Capsule?
