That Toshiba unit uses a DisplayLink chipset internally. On Windows it probably works fairly well, but it may be sensitive to which Windows version is being used.

On the Mac side DisplayLink has had no end of trouble producing a fully functional and stable driver. Two years since the driver was last stable with dual displays, for example. I use a DisplayLink docking station with my MadBook Air and I am limited to a single external display despite the dual video ports on the unit.

Just a heads up to verify the Windows driver compatibility rather than assuming it will all just work.

Looks like the linked Dell product also uses DisplayLink chipset.
