I love the convenience of the iPad but there are times when I miss Windows apps. It is not just for work; there is nothing on the iPad to rival Jack Bridge, for example.
The solution is to run Windows on the iPad via remote desktop.
Most versions of Windows have remote desktop built-in, though you do need to install a client on the iPad. I have tried several and settled for the moment on Mocha RDP. If you tap the up arrow at bottom right, you get a toolbar which controls the on-screen keyboard, extra keys useful for Windows, and a menu with options including a macro of pre-defined keystrokes. It even works with my cheap iPad keyboard.
The downside of this approach is that Windows needs to be running somewhere on your network. However Mocha RDP supports wake on lan, so you can turn it on remotely; note that this normally needs to be activated in the PC BIOS.
In my case I already run a Hyper-V server, a free download. I have installed Windows 7 on a VM (virtual machine), so it is always available.
The iPad also supports VPN (Virtual Private Network), so given a decent broadband connection I could connect to Windows while out and about. Alternatively there are systems like LogMeIn which do not require a VPN, though you have to install the LogMeIn agent on the target PC.
The general approach makes a lot of sense to me. Technically it is a hybrid thin/thick client approach. An iPad or other tablet is smart and has its own local apps and storage, but does not attempt to provide the full capabilities of a PC or Mac. When you need that, you can log into a remote desktop.
It is another example of how the mobile revolution is making us rethink how we do computing. The thin client concept is nothing new, but it is only now that it is becoming compelling for users as well as administrators, giving them the convenience of a tablet as well as access to rich applications like Microsoft Office.
Microsoft no doubt has its own plans for combining tablets with desktop-as-a-service. I would guess that it involves Windows 8 on ARM; but it will take some effort to tempt users away from their iPads.
