Windows XP at home, Ubuntu at work.What is your primary os?
My mother is the super star, she has two Windows XP laptops, one Ubuntu laptop, and a iMac running Mac OS 9/X. The Mac hardly works with any hardware and is a tad slow for OS X. The XP laptops have issues occasionally, poor software, or dubious hardware: low power USB ports, but they can be made to work with a digital camera, webcam, scanner, bluetooth pieces, etc. The Ubuntu laptop is very light and easy to travel, works very reliably: even gone through distribution upgrades with no fuss. Can you imagine your mother upgrading XP to Vista, or Mac OS Tiger to Leopard without asking?
