I can't make this decision for you. While I like MSFT's design choices, the draconian restrictions on Windows 8 RT plus the past history of Microsoft on they last Windows RT OS show us that the device is only for those that can live with all that I presented here.
Windows 8 RT is not a Windows Ipad. Windows 8 Pro might be that but what we have come to accept as Windows features such as installing our choice of software does not exist in Windows 8 RT. Windows 8 RT also does not run any prior Windows apps even if the restrictions were lifted.
