Just an advisory to avoid Earthlink DSL. I liked them when I first signed up with them, but then I left and came back. It was 1.5Mbps/384Kbps originally. The second time it became 1.5Mbps/128Kbps. Both $49.99/month and a one year contract. The second time I signed up they even tried to screw me out of a new modem (they didn't send one) but still put me on a one-year contract. A few months later when I had to keep calling about problems with disconnections and they said they'd send me a new modem but I'd have to send back the old one. I told them the old one was mine, they never sent me a new one when I re-signed up for service. When the modem was sent it had a note to return the old modem with 30 days or I'd be charged $150. I fired off a not-so-nice email that told them that they'd better not charge me for the new modem, and that if they persisted I would send back the new modem, demand $150 in credits for service, and to be taken off the one-year contract or I'd go to my state attorney general. They never replied to that email, they also never charged me $150 for the new modem. Once my contract is up in June with them I am switching to another high-speed provider since Earthlink is on my manure-list.
From what I have read about those accelerated dial-up services, they simply compress the web pages before they get sent to your computer so it works well with text pages but is no faster for file downloads. Probably a good choice for most people since they just browse the web and get their emails, but real high-speed is better if you like to download lots of files. Does Netzero still have you install that software which takes up 25% of your screen real-estate for ads, or did they eliminate that with their paid service? I used Netzero ages ago when they had completely free service, and the ads annoyed me enough to find another provider.
