Fruitcake of bozons
I have never ever heard before about InfoPath. IMHO the original idea was probobably to make yet another vendor lock-in in big businesses and collect license dividends for years to come. From screenshots and Spoogle I could see that it looks very much like a poor beta of FileMaker - yet another "database for folks" product.
I am pretty sure they will come up with some web based Kraken-coded Sharepoint Spin-off tool. And as it was said... simplicity of Dropbox makes it LOVED by users.
PS And one more thing. Expect more product deaths. Google started it. This can lead to innovation-through-extortion. I mean - it's cool that new ideas get implemented... but in the end it all boils down to # of licenses and cash streeeaaaaaaaaaam.
