Tablets aren't PCs either, at least in SST space, I just did a netsh command on my 8" Dell Venue Pro (troubleshooting some network issues) and let me tell you not an enjoyable experience....That's where the thinking breaks down, tablets aren't phones. Phone and phone app market share is so far underwater it's lower than the Titanic and probably right next to MH370. Now there's this gigantic Albatross being hung on tablets with a phone mindset that's produced nothing in years.
I wouldn't be betting my future on that because the strategy has worked so well up till now. /S
A Mouse and Keyboard UI will not work with Touch Base Machines and fewer of these devices are shipping with External Monitor Support (outside of Miracast).
