Doing more does not necessarily require a new operating system, it
might just require an application upgrade. You might be right,
screen reader developers might be working hard to make their
applications compatible with Windows 8, but you need to hear from
real users about that. The idea of getting an application out the
door in close proximity to the release of a new operating system
is not very meaningful unless the new operating system allows your
application to do things that the old operating system doesn't.
And again, you need to depend on serious users or authorities who
you know. I certainly wouldn't take the single word of one
developer that is trying to sell a new product to you, if that's
what you mean. You ramble about the newest and greatest operating
system, but you need to explain why Windows 8 is superior to prior
versions, with respect to the applications that you use.
In other words... Why is Windows 8 superior to a blind user? What
will Windows 8 blind user applications do that windows XP or
Windows 7 won't do? Does it support a critical piece of hardware
that you cannot currently use?
End-users simply do not shop for an operating system. Microsoft's
most recent operating system does come with a new computer, but
applications developers support prior operating systems especially
when there are more users of those prior operating systems. And in
fact, Windows XP is still being supported by Microsoft because so
many businesses do not want to upgrade. And lastly... If it ain't
