This article has actually been a pretty good advertisement for me. If I need some quick, cheap servers for non-critical stuff, I will definitely consider using this.
If you are interested in slow but usable, no they are not.
I bought one early and any network connection to the server is hellish to maintain.
There are plenty of cheap options that actually work, choose one of those.
Thanks for the advice. I would still consider at least trying them, as I've seen VPS providers change a lot over time. I did see the links posted here to other cheap VPS's, so I'd check those out too.
