Those of you with older devices.

I recently posted asking what everyones device setup were, well quite a few of you had older devices than I was expecting. Most of you even had the latest software editions of your choice of OS. So those of you running older devices, how is the performance of your computer running either OSX Mavericks or Windows 8/8.1? Has the newest renditions of the operating systems breathed new life into your computers or has it had an ill effect with your go to computer?
