I have multiple devices - iPad, iPhone, Mac Book Air, Sony Windows Laptop etc and if I could only have one device it would be the MacBook not the iPad. The reason is that while the iPad is good for doing the quick this or that it is so limited and so fussy in doing quite simple tasks that I reach for the MBA usually instead. So for example nothing with Flash works on the iPad (you'll find out how many sites use Flash and are not usable), it has no capability to edit Office sourced documents (Word, Excel, Powerpoint etc) and the Apple versions fail if you have pictures or tables in your documents and it has no accessible file structure to allow you to save, open and move stuff around if it e.g. arrives as an email attachment. You cannot easily switch between programmes - say going from CC to a web search to cutting a photo off the web and pasting in a CC post. Typing and editing is a pain because of the one handed keyboard and the frustrating text selection mechanism involving poking the screen. The beauty of the MBA is it comes on and turns off instantly like the iPad, it has a proper keyboard and software and its small, light, rugged and very thin. It may be challenged this year by a whole load of ultrabooks which are very thin lightweight laptops which meld tablet and keyboard if you want similar to the MBA but with Windows (although you can dual or single boot Macs to Windows if you want). My ideal compromise doesn't exist would be a 11" MBA with inbuilt 3G connectivity, a touch screen, an iPad emulator loaded up with all those useful apps and a keyboard that could fold right round onto the back of the screen to make it a tablet.
