Thanks for the interesting observations here on Win 8.
Personally, I would not recommend Win 8, in it's current configuration, to casual users and ,certainly not, to business users.
I got the preview copy when it was first released and it looked ok. I'm rather old school and prefer my computer to be functionally a tool. And my other devices to be, well, other devices.
I understand the overall logic in Microsoft's decision to go with a multi-platform OS, given that they service several markets. But, a desktop is not a laptop, is not a notepad, is not a cell phone, etc.
I purchased the upgrade to Win 8 Pro. However, I will wait until I have seen several more of those "Install this update to correct issues with Windows" updates before I begin to use this OS full time. BTW, currently using Win 7 ultimate.
Thank you for your time. Have a great day!
