True, Chrome OS is pretty cool. But as you say, the side-by-side PowerPoint/Keynote trick is a no-go (at least for the time being). And what would I do without my massive DEVONthink databases? Well, the short answer is, I'd probably virtualise them (put them in the Cloud somewhere). But there's something in me that resists this total abrogation of control... ;-)

You probably couldn't pull off the side-by-side PowerPoint trick, and
for now there still doesn't seem to be anything matching the
sophistication of Scrivener or ConnectedText online, but it's an
incredibly smooth experience otherwise, especially on some of the higher
end higher spec'd Chromebooks like the Dell Chromebook 13 with 8GB RAM
and core i5 processor.
