Depends on how "thin client" you want to go, probably.  If your apps  
are actually mostly running on an EC2 instance in the cloud rather  
than on the local device, a PXA might do just fine.  Though something  
with some better internal I/O switching like an iMX might be better  
depending on the app.  The issue in all these cases in the US would  
definitely be the pipe width between you and Amazon (or wherever)  
though, especially in the upload direction.
