There is great outrage to Microsoft’s reluctance to play ball and support virtualization of IE. Without an alternative, the solutions offered by Microsoft are expensive, cumbersome and difficult to maintain. Virtualising the application may well allow different browser versions to co-exist – but the user-experience can be cumbersome with links to other applications not always launching the correct browser and users having to know which browser to choose. Unibrows offers an interesting alternative utilising isolation to support the deployment of different controls and centralisation to allow management and control and importantly wrapped up in what sounds like a very appealing cost.
