The Verdict

So the "One OS to Rule Them All" is here. Actually, those of us participating in the Windows Insider Program" already had their launch copy of Windows 10 as of last weeks RTM download. Surprise Surprise. Windows 7 / 8 users will get their free upgrade soon, those who requested the upgrade via the task bar app getting it first. Updated drivers from hardware manufactures are here or on the way. There is of course no reason to be in a hurry about upgrading. The free offer is good for 1 year. Still, if you are a Windows 8 / 8.1 user go ahead and upgrade. If it runs on Win 8 in all probability it will run on Win 10. Haven't had any problems with my Win 7 apps either. Is windows 10 worth giving up 7? For most of us, yes. Sure you will lose Windows Media Center and native DVD movie support. USB floppy drive (not internal floppy) will require a 3rd pty driver. Still, you will be getting an OS that boots faster and is optimized for the new SSD drives. System Image Backup that was introduced in W7 and required a detective to find in W8 is back and is quite easy to find. I still don't know why they call it Windows 7 backup. Windows 10 will soon support DX12 devices and already supports the new biometric security standard.
