I'll give you 2 non-techy reasons:
1) Windows 10 is free
2) Windows 10 drops the Start Screen that everyone hated in Win8.
Speak for yourself. I love the Start screen now. It's uncluttered my life. I don't understand how people still use the garbage Start menu of old.
I hate that start screen; good reason.
Forced updates- AND who’s to say we won’t be forced into a ‘pay by the month’ system like adobe CS did AFTER everyone finally gets windows 10? How will we resist it if websites won’t work UNLESS the latest windows update is installed?
Hate the ‘new improved’ start menu- I didn’t want an ‘improved’ one- windows 7 start menu was perfect just like it was- there should be an option to retain windows 7 start menu EXACTLY like it was, or use the new one- STOP changing what isn’t broken and works perfectly well!
Don’t like the idea of apps ‘phoning home’ with no apparent way to disable the phone home part like we can in windows 7 programs
Forced updates- means a program that works now, might not work AFTER the update, but we won’t have a choice to pick and choose the updates we want now- meaning programs We’ve paid money for, may quit working- In windows 7 we could opt out of known combustibility problem causing updates- no longer though
