It takes a strong personality to admit that they've changed their minds.
I'm currently working on a relatively complex project where we are producing and updating lots of UML diagrams. I was discussing with the BA on project the fact that Visio is well, pretty horrible, and that the most natural way to create said UML diagrams is freehand. This led me to wonder if there were any Tablet-based tools for UML entry, which in turn led to TabletUML (my verdict on which is basically that it has some rough edges but overall it's pretty impressive. And quite a pleasure to use) - so anyway, having identified a promising-looking application, we arranged for said BA to get an HP tablet on loan to try it out.
I have never seen such a serious person grinning so much just as a result of using a tool, and I've got to say I understand entirely: the handwriting recognition really works now (it even handles my scrawl with aplomb), and the redesigned input panel makes ink entry and correction child's play. I've never really believed the hype about tablets previously, but this latest incarnation of the OS really does make it seem like a more natural way to work (that sounds like a bad advertisement script but it's actually true).
If only I'd have a visit from the headhunters so I could afford to buy one...sigh.
So anyway, I'm taking this opportunity to give credit where it's true and congratulate Microsoft on a job well done (but I promise normal sarcasm will be resumed after this transmission).
