I pretty sure Google knows all of this. And are counting on it. They want them in people's hands, and they know once they are, all of those problems play into their vision.
And those people don't know what Google Docs are either. And when they get an Excel document where charts don't render correctly, or comments are screwed up, or pivot tables don't work against their datasource, they'll be POed.
Google likes this. Excel screws up? Perfect, just use Google Docs. Mission accomplished. People are surprisingly flexible if you throw up a barrier. An hour or so of pissing off a customer is a exchange Google is willing to make if it give them a shot at a new Docs user.
Or when all their friends are playing WoW and they realize that this device doesn't play it.
Really? Hardcore gamers are the last people who would use this, and the first people to recognize that.
Or when they want to Skype with their grandkids they realize, they can't do that.
Hmm, Skype doesn't work? I am sure the company with their own browser based video chat system is crying a river.
Or when they take the photo editing class and realize that the laptop doesn't run the software so they trot halfway across campus to use the lab that has the software installed.
As the owners of Picnik, they are again very angry, I am sure.
Or when they go to get all their stuff on iTunes and sync their iPhone with it and realize that they still need their old laptop.
Apple uses their mobile platform to encourage people to use Macs, why can't Google encourage use of their mobile platform with their laptops?
There are always going to be a million reasons why a new device won't fit the current system. But Google is making a big bet on the future, and for my point of view, this seems pretty ingenious. And an utter cash cow if they pull it off.
