Speed depends on where you live too. For the most part, it's fairly good enough to use as a home internet connection to replace dialup. It's much much faster than dialup even on the worst of days. Where my parents are located, the tower is only 10km away, so the data is quite consistent, and good enough for their needs - to stream a bit of video, post pictures online, send emails, that's about it.
The $65 one is if you already have MTS Highspeed internet, I don't know if dialup will allow for that $10 discount, but hey.. if you're going to get an internet stick, I don't see why you'd stick with dialup anyways?
I have friends who have used Skype (which is in a way, similar to VOIP) and they have no problems at all on MTS internet stick.
What do you plan on using the internet for? If it's just sending emails, a bit of watching video, and some browsing internet sites - you won't have to worry about throttling, but even at throttling speeds - it will still be FASTER than dialup.
Man gets hit by Brick Phone! Ouch!
