Welcome to our forum.
I just bought 86 HP NX6310 laptops for the hospital I work at. These are going to be true mobile wireless devices as they are all mounted on a clinical carts in which clinicians will be using our main Electronic medical application throughout the hospital. We're not gaining much as far as performance with the Core Duo as our application is hosted on a 50 server Citrix farm, and the processing and memory for the client app is all being done on across the 50 servers (again Citrix). The servers are HP DL360’s, dual CPU, 4GB of RAM, , and running Windows 2000/2003 server. We get about 40-50 users per server.The real benefit to the Core Duo processor on these laptops was the power savings, which when using wireless mobile carts, battery life was certainly something we needed..I don't keep up too much these days with the latest desktop hardware, I mostly do server/domain/network design and support now and my focus is in that arena.
