it's light, the pen's v. easy to get on with, its got all the wireless bits and bobs etc. etc. the keyboard is detachable and the dock looks very stylish
overall its a very good machine
we do have a lot of problems with the system board failing, but they come with 3yr warranty, so it doesnt cost anytihng to get it fixed. on average we have 1 a month fail (from a stock of about 400?)
the spec is a bit dissapointingtho, theyre only 1.0 Ghz machines so they can be a bit slow at times.
perfectly adequate for work purposes tho, and with 1GB memory they cope quite well
