We're looking at adding a new desktop workstation and a new mobile workstation / laptop to the office. any one have any recommendations for a good quality reliable not too expensive laptop suitable for REVIT?

any one look at OriginPC's ?
or SAGER's laptop (been around since 1985) some of their mobile workstations look pretty nice.

We used to do Dell, but support and quality dropped over the years...
We have a lot of HP's and they seem to be good work computers, but a few breakdowns there too.

I use a i7 ZT-Systems workstation and it runs nice too bad they don't make desktops anymore and never made laptops.

I'm thinking as a starting point a REVIT laptop will have to be:
an i7, 64 bit OS, win 7 (no Win8 yet)
8 or more GB RAM, hybrid 7200rpm HD or better
17" (or 15" plus 2nd larger monitor)
Nvidia or equal graphics

a bit thin on specs but you get the Idea.

I use Revit on my sony i7 64bit system with a hybrid 7200 HD 6 gb, etc and it's doable, the hybrid drives help a lot.
