Perhaps this is the wrong forum to post this question. I have recently moved from winxp to Linux because I got fed up with the continuous cycle of rebuild, slow down, crawl of the winxp OS. It seems no matter what you do to a win machine it will eventually get slower and slower, boot times, launching apps, etc. Linux claims not to suffer from this and in my 12 months experience it does what is says on the box - it runs like a dream. My mother-in-law has recently purchased a mini mac, son a Powerbook and a friend has asked advice on a new laptop because their current machine (winxp based) is now crawling along! I feel like advising my friend to move to mac/OSX but I have no long term experience - does mac/OSX suffer slow down over time as per windows machines?
