A User client will cover a particular user's access to the server software from work PCs and laptops, as well as from home PCs, PDAs, Internet kiosks, and other devices.Per-User vs. per-Device: purchasing a Windows® User client might make more sense if your company has a need for employees to have roaming access using multiple devices.
