Can you be as productive on a mobile device?
I don't know about you but the thing I love about my desktop is the size of the keyboard (I can type faster), the ergonomics of my mouse (it's too large to travel with) and my dual screen setup that allows me to have a PDF open on one screen and a Word doc on the other. I also enjoy the fully functioning apps that I can enjoy on my large screen and while multitasking within a single program (ie Quickbooks reports, invoicing, etc). Sure you can dock a laptop and get the same effect, but desktops are a lot better value for the power and quality. Currently a fully functional Quickbooks does not exist on any Android or Apple tablet or mobile device. Last time I tried to change my Google password on an iPad it was a pain in the rear. Windows 8 bridges the gap between mobile devices and laptops / desktops, but it is not apparent at this time if Windows 8 will be successful. Lastly, I'm sure many of us travel for our jobs but many of us don't. Even if we work from home, we don't necessarily need a mobile device to get work done. Right now, you can't beat the value, the speed, and the productivity that a desktop provides. Personally I'm sick of these articles that keep predicting the death of the desktop.
