Re: A serious question for a change...
Apparently Narrator has improved a great deal. As a test, I had my blind colleague run it for the morning - because this is interesting stuff and it applies to our own software as well - and he claims it's "good enough for work". I also ran diagnostics on the PC he was using (i3, 4GBRAM test box) and it did not appear to feel any strain from the extra overhead.
Obviously, that's some way removed from an Atom with 1GB regardless of Haswell's improvements but it's something.
