Everyone is all excited about the new presentation/slideshow feature that's coming to Google Docs & Spreadsheets. I say "where's the beef?" Google's docs and spreadsheet service has been around for quite awhile, but have you actually tried it? I tinkered with it once, several months ago, and never went back.
Let's face it: Corporate adoptions are what makes Microsoft Office the cash cow that it is. Despite the obvious licensing fee savings, how likely is your company to switch from Microsoft to Google? If cost is the driving force in this sort of decision we'd all be running Linux on the desktop right now. Clearly that's not the case.
Adding a PowerPoint knock-off isn't going to change things much at all. Will anyone use this? You bet. Will it kill Microsoft Office? I seriously doubt it. Google needs something more compelling than cost to get customers to switch.
