IMO, Dell Latitudes stopped being business-quality and started being consumer-quality _many_ years ago. Crap keyboards, crap touchpad, cheap painted plastic case, etc. You need to step up to at least the Precision line to get anything decent.

Although, Dell have refreshed all of their product lines lately, so even this is outdated advice. Looking through their current lineup and I don't see _any_ with real physical touchpad buttons or pointer sticks, unfortunately.
