If you've sat the 70-620 or even the 70-623 then you'll have little problem with this exam as it's more of the same, with the 'Windows Home Server' questions slapped onto the end.
Passed 870 or something as, again, the testing location couldn't print the results.
That's the Vista client exams over for me but I 'might' take the 70-624 when a book becomes available or just ignore that for the Windows 7 exams (When they arrive). These exams, especially the 70-622, have been fun, with the questions being less cryptic. Overall, the 70-622 is a vital exam for admins and I'm afraid to say that most will ignore that exam, opting for the 70-620 alone.
Next: 70-271 & 272 then 291. (I realised that I should have taken the 271/272 then the 621 but heck, why not do them all)

Woooo!
