Intel Pentium 4 processor at 2.0GHz. Compare prices before you buy. My friend has a small business with 3 employees and they use the Internet all the time.
Connectivity is as necessary as electricity in their offices.
I have been there numerous times, e.g. to install hardware and firewall software. Things worked sort of ok when I was there in February except for weekly outages, lasting a few hours each. I have tried to live with Telocity for about six months now. I eventually wrote to every email address in their system and received a response from a guy in billing who credited me for three months service.
