The majority of us are probably using a touchpad on our laptops and the scrolling thing is just horrible in that case.
The target customer will expect easily laid out information (as this is a web-based monitoring service) and if they see this "at the front door" then they'll run a mile.
The design looks solid. I don't know anyone that has troubles scrolling on their laptop these days. I found that quite bizarre to hear. With daily use, you can be nearly as nimble as using a real mouse.
Could you give some suggestions on what you would change? I'm curious how you would display that much data on the screen in a clean manner.
Not trying to argue here, genuinely interested in improving my UI/UX knowledge. Quite useful when building webapps these days.
That is a terrible website considering your target market are UNIX geeks.
