I own one PC - a Dell Optiplex with Windows 7 Professional on it and two laptops - a Lenovo i5 Thinkpad that I purchased second hand three years ago and it is still in great shape - also with Windows 7 Professional, and a Toshiba Ultrabook laptop that I use mostly when I travel as it is so light and easy to travel with. I reformatted my PC - the Dell Optiplex at the end of last year and added memory to it - it now has 16 GB memory. Hard disk is 500 MB only but I work mostly with external hard disks for storage, so no problem. After I reformatted it and reloaded Windows 7 Professional it was like a brand new desktop. I'm almost certain, provided there aren't too many new OS development that deprecates Windows 7, that I can use it for another two years.
