Oh yes, you'll notice a HUGE difference - particularly when downloading software updates and things like that. Large files that used to take hours will take minutes. Web pages will generally load faster (maybe 3 to 5X faster - not as noticeable as when downloading files, which will be up to 20X faster) and you will be able to watch most streaming video. YouTube works fine with 256kbps from what I've read, so 1000kbps should be more than fine for that. As noted, your Mac may have problems though. (Maybe time for a new one?)
And you won't be tying up the phone line either!
Go for it!
One question - are you sure that it's DSL? Comcast to my knowledge has no DSL offerings - not in MA anyway. Verizon has the DSL market in MA, as far as I know.

A much better deal than losing tv channels and only getting 1MBps internet, IMHO. I had the odd issue with Comcast when I was living in MA, but overall the service was usually pretty good. I used them for probably 8 years and during that time only had one long-ish outage of about 2 days, for which I got credit on my account. There was the odd outage for an hour or two, but other than that, generally good. The cable TV was excellent. Now, IF North Andover had had fibre optic, I would have been very interested, but for some reason or other, Verizon laid the cable in Andover, but skipped North Andover. Regular DSL was also hard to get in North Andover - few people lived close enough to the telephone switching stations to actually get it.
