I ordered the Kingston SSDNow drive and easily upgraded my home PC following the simple instructions. Cloning my existing hard disc was easy and as I keep an orderly ship the 34GB of operating system and programmes were transferred in less than 8 minutes. I was up and running in 10 minutes. I use Windows 7 and everything is faster - start up, anti-virus scans, programming. I use a portable drive to store my Outlook PST files and Outlook operates easily and much faster. I also use ArchiCAD and again the speed of the SSD was a real boon to my 3D modelling. For info my stystem is a home built quad core processor, 4GB memory, 1GB HDMI graphics card. My PC now starts faster than an Apple and is laughingly more powerful than a G4 costing 2, 3, 4 or even 5 times the price.
