Is anyone using an external hard drive with TIVO to go and their laptop? I was just looking at a Maxtor external drive with 80gig for $100 (haven't really price shopped, so this is just a starting point). Rather than purchase a new laptop, could I just as easily store programs on that and bring it along? Looks small enough to just toss in the carry on bag. I only have 12gig free on my laptop, and this looks like a good workaround instead of buying a new laptop with a bigger hard drive. I could move programs onto the laptop as space clears (or I guess I could view them directly from the external hard drive if I'm parked in a hotel for the night). Is this workable?
