Wyse has updated their PocketCloud product and have now made it free! (from a pretty expensive $30).
Wyse PocketCloud is a free app that allows users to access their PCs or Mac computers or virtual environments remotely from their phone or tablet. PocketCloud has been optimized for iOS with a highly accurate Touch Pointer, custom keyboard with short-cut keys, and enhanced sound support using RDP for different connection types encountered while on the move. What’s new in Version 2.2? The iOS update brings multitasking to PocketCloud on the iPad, iPhone, and iPod touch. This enables users to connect to their desktop, send the app to the background to answer a call, and return to PocketCloud retaining the connection to their desktop. The update also increases performance under iOS 4.2.
