I remember them (they were known a "digital pens") from a few years back but I haven't seen any around for a while to be honest. They never were very popular as they simply didn't work particularly well.
All the ones I saw had to be used with special paper that had a microscopic pattern of dots across it so the pen's camera could work out which way the pen was moving. This made them expensive to use in the long run as without the special paper they didn't work.
Handwriting recognition is always a bit of a lucky dip, too; sometimes it works great, a lot of the time it's more hassle than it's worth as it doesn't read the words reliably and so you're left trying to work out what "important - hyfyglky snnoab pfui" means.
You need to write very carefully and clearly for handwriting recognition to work reliably. That would rather defeat the object for you as it would slow down your minute taking.
How extensive are the minutes you need to take, and how vital is it that they're 100% accurate? You may find that a digital voice recorder (or Dictaphone, if you want to be all 20th Century ) works better as you can then just type up the important bits later on.
