Con - the button to eject the CD drive is WAY too stiff - the whole computer moves first!
It turns out that my current versions of Acrobat and Omnipage pro are too ancient for Windows 7 - I had a feeling that might be the case. REALLY wish I'd done this while I was still an educational user, that's an extra money hit which could have been smaller but it's pretty much essential. Bit the bullet and ordered them anyway.
More once I've finished installing everything. For now reasonably happy.
