I ran across a piece yesterday discussing one hospital’s lack of success with iPads and BYOD. My curiosity piqued, I examined the piece looking for where the project failed. Interestingly, but not surprisingly, it seemed that it fell apart not on the iPad, and not with their legacy application, but in the symphony (or more realistically the cacaphony) of the two together. I can’t be certain that the hospital’s solution is using Virtual Desktop Infrastructure (VDI) or Remote Desktop (RD, formerly Terminal Services) to run a legacy Windows “desktop” application remotely, but it sure sounds like it.
I’ve mentioned before how I believe that trying to bring your legacy applications – applications designed for large displays, a keyboard, and a mouse, running on Windows 7/Windows Server 2008 R2 and earlier – are doomed to fail in the touch-centric world of Windows 8 and Windows RT. iPads are no better. In fact, they’re worse. You have no option for a mouse on an iPad, and no vendor-provided keyboard solution (versus the Surface’s two keyboard options which are, take them or leave them, keyboards – complete with trackpads). Add in the licensing and technical complexity of using VDI, and you have a recipe for disappointment.
If you don’t have the time or the funds to redesign your Windows application, but VDI or RD make sense for you, use Windows clients, Surfaces, dumb terminals with keyboards or mice – even Chromebooks were suggested by a follower on Twitter. All possibly valid options. But don’t use an iPad. Putting an iPad (or a keyboardless Surface or other Windows or Android tablet) in between your users and a legacy Windows desktop application is a sure-fire recipe for user frustration and disappointment. Either build secure, small-screen, touch-savvy native or Web applications designed for the tasks your users need to complete, ready to run on tablets and smartphone, or stick with legacy Windows applications – don’t try to duct tape the two worlds together for the primary application environment you provide to your users, if all they have are touch tablets.
