I have been running Windows XP for many years. Other than my unfortunate experience with Toshiba and the Tecra M4 Tablet, my experience with XP has been excellent. Since moving to my Lenovo T60p I have had the most reliable and productive work system in my experience. As many of you may know, Microsoft has announced the end of XP, however, their replacement, Vista, has not been well received by the IT community. (I do run Vista on my wonderful Lenovo X61 Tablet PC and as a Tablet OS it's the best, but I do feel like my productivity has taken a huge hit compared to XP.)
If I were forced to choose between Vista and a Mac OS on my primary machine, I might switch. My past concerns that key programs that I needed were not available for the Mac are gradually going away; some of my favorite productivity tools: Lotus Notes, eProductivity, Personal Brain, and MindManager all run on the Mac.
I would prefer to remain on my present laptop with XP; it is my most productive tool. Windows XP works great and I love the variety of Windows programs available to increate my productivity (e.g. GyroQ and Activewords, to name a few.) However, when I need to purchase my next computer, if Microsoft will not let my purchase XP and if they have not fixed all that is broken in Vista, I'll explore other options.
If you would like to see XP stick around, there is something you can do. InfoWorld is trying to get 300,000 signatures. From InfoWorld:
Microsoft plans to end most sales of Windows XP on June 30, despite a deep reluctance by many business and individuals about moving to Vista. InfoWorld believes such an expensive, time-consuming shift with problematic benefits should not be forced on Windows users, so we have decided to rally XP users to demand that XP be kept available.You can do your part to save Windows XP, here
