Once upon a time, it was essential kit, but lack of development, a king's ransom in pricing, and no intel version have the masses crying out for a decent alternative. The current version is unreliable at best, and not especially easy to work with. The only redeeming feature is the video/motion capture function, which either doesn't work or doesn't work well. Not worth your money until they come up with a decent update, or are hopefully replaced by a competitor who cares about what they are doing.

This update has done nothing except WASTE my time... I recommend not updating since this seems to have caused numerous performance problems. I use Word everyday for work, and can't understand why MS would release such garbage, in spite of it's billions of dollars and thousands of hard working professional programmers. With resources like that, they should be releasing the finest stuff on the market. Clearly they don't care, since it is nearly impossible to make bug reports.
Since the update:
1) I cannot delete a block of text after highlighting. It only will work by deleting characters individually.
2) Charts can't be copied & pasted, only text.
3) Noticable slow downs - text frequently takes several seconds to appear after typing, creating a sticky effect. Yuck.
Thankfully, there are alternatives that are actually fun to use and work. I'm recommending our company dump this junk.
