Lately, I've been hearing how the wave of the future is to fix someone's computer remotely. Some are selling their services on a monthly or yearly subscription type of service, so if a user (typically a non-computer saavy person) is having issues, they can call this same company up any time, and for the price of a monthly fee have their computer looked at and fixed. (at least software-wise)

Is this kind of thing catching on more and more? What are your opinions on them?
