I've been looking for the ideal machine for building and presenting solution demos and I think I have found what I'm looking for in the NextDimension mobile PC from NextCom LLC. This laptop can be outfitted with 16GB of memory, has 2 dual core Opteron processors, three 1GBit/sec Ethernet ports and an internal RAID 5 system with upto 1TB SCSI storage capacity. And as ComputerWorld reports ..."if your mobile users need more power than it provides, get them a mainframe and a pickup truck"
