It depends on use. Data entry systems? Nope, mobile not required. But changes Windows over the next few years will force those to be a WinRT app rather than a Windows desktop app.
>Agreed. The market has clearly been moving in that direction. Heck, a new app should probably be mobile enabled as well. PC desktop apps have had their day in the sun. IMO it's going to be mostly legacy work from here on out.
