Well if you have Windows 7 licenses then not really but eventually you will need to switch. I'm mainly switching because I'm running out of Windows 7 licenses with all the computers around here, that and my laptop has it so I'd rather just use one Windows OS and be done with it. It just helps if there are any problems. Windows 8 is more geared towards tablets (start screen interface at least) but once you get a start menu replacer it's a normal pc again and by it being made mainly for tablets it's much faster and lighter on resources.
Is there any reason to upgrade from windows 7 to windows 8? I mean I don't really want to do it if there's no point. I was also under the impression that windows 8 was more geared towards tablet pcs and touch screens.
Windows 8 is really not as bad as people make it out to be especially if your hardware supports it. I have yet to try it on my Desktop (Windows 8 Ready Motherboard) but even with fast boot disabled on the 5400 RPM HDD of my laptop (I use my SSD now) it only took maybe 30 seconds to boot. Which for those that don't know is comparable to the slowest Linux. Plus once you have a start menu replacer life's smooth. I do need to install the SSD in my Desktop though I just keep going back and forth on buying the Student Edition of Windows 8 Pro ($59.99) since I do still need to replace my GFX card since my desktop's GFX card is puny.
