When Microsoft released Windows 8, I wasn't enthusiastic about it after I had seen and ready about it. Eventually MS released a cheap upgrade ($40 to download a key and ISO) which I jumped on. At the very least I wanted to take it for a spin. After 2 or 3 months, I just didn't like it. It worked very well and everything ran fine, but I didn't like the interface (even with having installed a 3rd party app to add the start menu). So I went back to Windows 7 Pro, but now that Windows 8.1 SP1 is out, I'm curious again. This time, I'd like to hear from people that have tried it, especially those that ran the earlier 8.0 version. What do you guys think?
