Yes, after over a year of Bell Atlantic 640/90kbps ADSL, I decided to pay for the big switch to SDSL. I've just recently had it installed, and here are my observations so far:
* Lower latency--I now ping my friends' campus machines at 20ms, compared to 50-60ms with ADSL
* Comparable downloads--with ADSL, I could get just over 60KB/sec from the best servers; now I max out around 75KB/sec. However, from most servers I never reach this speed (thus no advantage is experienced).
* Bandwidth is utilized more readily--when I had ADSL, the downloads would begin at lower speeds, around maybe 10KB/sec; then the speed gradually increased, approaching the limits. With SDSL, I seem to instantly get full bandwidth, which sometimes accelerates web browsing a lot.
* WAY faster uploads--my previous ADSL connection tested at 520kbps down, 70kbps up; the new SDSL tests at ~650kbps both ways.
Overall I'm satisfied, but I hoped to get "fuller" bandwidth utilization (I wished for consistent >70KB/sec downloads, but oh well). The true test will be when I run domain/DNS, FTP, email, website, and game servers on a dedicated machine. We'll see what'll happen then
