Sirgod, I resisted the change for a couple of years. The main reason was that I was using a dial-up ISP (AT&T Worldnet) that for quite some time only charged me $14.99/mo. I didn't feel like giving that up for these exorbitant cable fees I'm paying now.
Actually, it was my wife that forced the issue, though she barely uses the computer for anything but e-mail and then only occasionally. I am the one who mainly benefits from it and no, now I won't change... the difference is too large to ever go back on, even if cable charges relatively, a lot.
Like you, I was amazed at how fast I could download at home... most often faster than T3s at work (even a dial-up isn't too bad when you're the only person using your computer for the most part!) because of all the goldbrickers shopping or chatting on the Internet when they should be earning their pay.
Incidentally, the straw that broke the cheapskate's back was AT&T's raising my precious $14.99/mo to a gigantic $17.99/mo. Boy, my veins popped. So, I said, "I'll show 'em- I'll shell out even more just to dog 'em!"
