Ask Slashdot: Upgrade to Windows 10 for accessibility?

BarbaraHudson writes: NVDA (Non-Visual Desktop Access) is a free screen reader (Windows only) with lots of features for people with visual handicaps. NVDA recommends delaying moving to Windows 10 because of problems with the Edge browser, pdf reading, Cortana, and applications designed for the Windows Store.

There's only a few weeks to "upgrade" to Windows 10. My question is, does Windows 10 have compelling reasons for the visually handicapped to switch to it that are worth putting up with these (hopefully temporary) problems? Please note that NVDA doesn't require an internet connection to work; Any Windows 10 assistive technologies that require one are a minus because they can leave the user high and dry with no notice.

BTW, I've tried the KNOPPIX Adriane Audio Desktop and unfortunately it's really not there yet in comparison.
