Just some food for thought, as I am also of the belief that tablets are not taking over anytime soon, however...
I work at a very large corporation. It is in the Top 100 of Fortune 500 companies.
The IT department is currently piloting a few different tablets in a few different divisions. The Surface, Lenevo's ThinkPad Tablet whose name is escaping me right now. And everyone right now in the sales force has iPads. Our IT department would love to replace those since we are a Windows based environment.
The best way to replace iPads? Find a Windows based tablet that can also replace users laptops as well, killing two birds with one stone so to speak.
So yeah, while home power users still very much have a need for a "traditional" desktop or laptop, a tablet may very well be sufficient enough in a corporate setting, and that is a huge market as many of you already know.
Really all it needs to do is MS Office for most corporate users. PPT especially. Not that many people in corporations are editing videos or opening Photoshop.
So this may not be that far fetched is all I am saying.
DL, we have been deploying the surface pro's instead of laptops and so far they are exactly we intended them to be, laptop replacements. We dock them using a usb doc, so the users only have two plugs to plug in. This gives them video, mouse, keyboard, and lan. The other plug is power. Users either use it in mirror screen or extended, it depends on the user. No one has complained and has welcomed the device over a laptop.
The entire package we give to our users, surface pro, 2 chargers (one for work, one for home or on the road), a type cover (which is a full button keyboard), a usb dock, a keyboard, a mouse, a monitor, two usb ethernet devices, and two patch cables (one for work and one for on the road if/when needed). The pro is more than enough for the majority of our users who mainly vpn in, and open office based applications, as well as web stuff.
So I would say that the ability to replace the laptop is quite there, provided you get the right one. We are a Microsoft and SAP shop.
