At work we had an auction on a number of older laptops that were replaced by newer machines. I got lucky and was able to buy a Dell D820 for my wife. Our tech support people did a great job testing the machines before we got them to ensure they worked and reinstalled Windows XP. I re-imaged the machine to PCLinux as a dual boot machine. It didn't take very long and it was running and my wife is very happy that she can now work anywhere in the house using the wireless connection. I left it as dual boot as she does use Microsoft Publisher now-and-then and this will allow her the option to use the program. My wife just loves the machine and it appears that her 'old' desktop may be repurposed in the near future as a server for our household. I figure that we can put the printers on that machine and then share it so it won't matter where we are in the house we can print to the laser or inkjet on demand.
My daughter got a new laptop at Christmas and I was storing her old Compaq desktop. I re-imaged that machine also to Linux and it will be going to my middle son and his family. It will be great for them as it is more responsive than Windows XP and more secure out-of-the-box. I also loaded a number of educational games for my grandson. Upside is that this saves them money buying a new machine and an older machine gets an extended life in a new home. Libre Office was installed so they can read and update any of the documents they have on their laptop.
