Downtown Toronto. A few months ago, service would just drop out and I would get nothing for several hours at a time. I (nicely) suggested that they refund a small amount or extend the service for that amount of time (about a day total) but I just got a curt email back from them (several weeks later) saying that nothing is guaranteed. Plus I'd get frequent dropped connections. Plus they never gave that free month to my friend who I said referred me. False advertising.
However, it's been great in the last couple of months. In Unreal Tournament I can get ping times as low as 35 ms off of servers in the US. (It's usually around 80 or so.) Despite the fact that I'm really just a mediocre player, I can often get in the top three of a deathmatch and win a game now and then. I find that once I'm over 125 or so, UT gaming suffers.
I find the biggest benefit, though, is that the computer is ALWAYS on the internet, and it doesn't block phone calls.
My guess is that no matter slow DSL is, it's still gonna be better than dialup. The main problem with Sympatico is that their software is crapola. The older version of Access Manager had a memory leak, and I couldn't run Windows 98 until I manually deactivated parts of it. (Dunno if it's now fixed - never bothered updating it.) And, I've uninstalled all the other useless Sympatico software. In Windows 2000 I am quite happily free of any Sympatico software - don't even use Access Manager.
