Well I still haven’t upgraded and I’ll have to wait until work eases off a bit before making the move. Meanwhile I’ve had time to think, and in that respect a review of mobile workstations in this month’s Develop 3D has been of enormous help.
www.develop3d.com/workstations/Reviews-mobile-workstations-for-cad-a-buyers-guide
The bulk of this page deals with the individual components, but if you scroll down to the bottom of the page there are links to each workstation reviewed and a link to a chart comparing the workstations. This is a UK magazine so a couple of models might not be readily available in the US. Also pices are in £.
The real surprise is the Schenker W503, but I think 15" might be too small for me. Also the Workstation Specialists WS-M1760, but that extra performance comes at a premium. I still think for my purposes the Dell 6800 is going to be the best option, but we all have different priorities so I’d encourage you to give the article a read.
It has to be said that the HP & Lenovo offerings don’t score very well, especially when you compare prices. The Schenker is a steal compared. Buy a Lotus for less tha a ford sort of thing.
