HP 2133 Mini-Note PC: HP was the next vendor after ASUS to introduce a netbook to the market, and its 2133 Mini-Note PC differed as it was aimed at business users, not students. It had an 8.9in screen, a VIA C7-M CPU (1.6GHz), 2GB of RAM, a huge 160GB hard drive, and it was the first netbook to run Windows Vista Business edition. It also had an ExpressCard/54 slot, making it a desirable choice for users wanting to use a 3G data card. It also had a tendency to get very hot, making it uncomfortable to use on your lap for long periods, and its battery life was poor. It cost $999 at release. A second version of the Mini-Note was released, priced at $899, which had a 1.2GHz CPU and 1GB of RAM.
