Lenovo has gone the extra yard with security considerations for its IdeaPad Tablet. Not only does it offer Cisco VPN and Good Technologies secure e-mail, it also lets you encrypt data on removable storage. It also ships with Citrix Receiver, so users can work with a remote Windows desktop under the control of IT. Your techs will love those features.
A tablet can meet at least some of your business needs, but it's most likely going to entail some compromise in the way you work. If you have software that requires Windows, then you need a Windows tablet--no way around it. If you don't have that constraint, then the iPad and Android tablets are more finger-friendly options.
