Not to provoke further, but an I don't consider an iPad a 'real computer'. It's running the same OS as an iPhone.
I also wouldn't consider a tablet running Windows Mobile xx (or Windows Mobile CE) a real computer anymore than my phone (which is not a real computer).
If they are taxing iPads, they better be taxing Windows Mobile devices, along with Android devices. If they aren't taxing Windows 7 (XP/Vista) devices, then they shouldn't be taxing systems running Mac OSX or systems with whatever the Google operating system is called nor anything sold with Unix/Linux on it.
The tax is stupid, but as long as it follows the same rules across all platforms then people should be upset about that, not comparing iOS to Windows 7...
Of course, the linked article doesn't actually give versions of windows this applies to, which is an important point.So I assume this is just to start a flame war because someone said their iPad is not a real computer...
