Puppy Linux and Toshiba Satellite with 4GB-Ram on one Core 1.5 GHz AMD CPU. The system is not machine demanding and the work is smooth. I like it, fast enough for browsing, email, notes etc. Puppy Linux, started by Barry Kauler, is a small, fully featured Linux distribution. Puppy works swiftly on older systems and is a delight on modern computers including netbooks and ThinPCs. Puppy boots to a familiar environment for ex-Windows users. Puppy is regularly updated and is well supported and documented.
