Testing Windows 8 Consumer Preview

Quick introduction, I'm a .net developer looking to get into Metro development for Windows 8 tablets. Having just splashed out on 'the new' iPad, I'm not in a rush to buy another tablet just to test out a bit of experimental coding.

So, my plan is to find a good RDP client for the iPad that would allow me to get familiar with Metro and to test out the usability of my apps. Firstly, can anyone recommend a good iPad RDP client that will work with Windows 8? Preferably one that has good multitouch support. Secondly, does this sound like a good idea? Can anyone think of a better way to get to work on Metro development without buying one of those expensive, bulky x86 tablets?
