I began on my iMac, using the VMWare Fusion version 5 virtual machine. Windows 8 checked, said it could upgrade my Windows XP just fine, downloaded, began installing and then notified me that it could not install on VMWare fusion.
Darn! I moved to my Sony laptop but, wait!! I had paid for what I downloaded to the iMac. How could I get it over to my Sony PC laptop? Finally I found a support number and talked with a very pleasant lady in the Philippines. She "took over" my machine and found the right web site, checked my receipt and all that, and got me downloading Windows 8 all over again, but on my XP partition on the laptop.
All told, even with my very fast Comcast connection, it took three hours to get Windows 8 installed. I thanked the nice lady, and we disconnected. It is installed. I used Internet Explorer to download Firefox and Chrome, messed with it a bit, and stopped.
Since then I have read more about Windows 8, and experimented. I downloaded Open Office, and it works very well. The networking took a bit of time to get working, even hard-wired, but it finds other machines on the network. I am getting the hand of the new interface, and finding places to go to tweak the settings. In a PDF I downloaded (for $9.95) I found the list of keyboard shortcuts. Everyone should have these who uses Windows 8, but I won't plagiarize and print them here. Find them somewhere on the web, pay for them as you need to, and learn at least the ones you use the most. Control+C, Control+X, Control+V and Control+S work the same as in previous versions of Windows.
I am concerned. My older clients may be buying a new computer and will have serious adjusting to do in order to use this well. They are all up to it, but may be turned off by the learning curve.
More in a few days. Meanwhile, share your experiences or responses. My next project will be finding out how to install it on my iMac. Let me know if you have figured out a workaround.
