In the weekend newspaper I saw this review, written without irony by a computer journalist, of a new piece of software:
"OneNote was developed by a smart team of developers within Microsoft, and it's a shining example of what the company is actually capable of producing.
OneNote works a bit like a plain-paper notepad. You can write anywhere on the page, draw and highlight things, and once something is written or drawn it is there permanently, with no need to save it."
A computer program that behaves just like a pencil and paper! I checked the publication date in case it was April 1st, but no.
At the relevant Microsoft page we are invited to "Try OneNote now: no download required" (just provide your own pen and paper?)
Or if you want to fix the bugs in the original version, they say you should "download OneNote Service Pack 1 (SP1)".
