Thumbstacks. Hmm…another online application, this time a Powerpoint type presentation app. OK, so it’s basic slideshow stuff, but it’s slick and fast and easy peasy to use. You’ve got to see the writing on the wall for kludgy expensive offline applications, if something as elegant and simple like this can pop up the drop of a hat. So where are we now? Online spreadsheet, word-processor, database (did we mention DabbleDB already?) and now presentation? Hmm, seems like a wrap to us. No wonder Bill’s off, this must be scary stuff for the boys over there.
