They did. In europe, both Fujitsu Siemens and MSI registered netbook trademarks of their own: amilo netbook and wind netbook. I'm sure they would have registered netbook if it wasn't already taken
However, many jurisdictions including Europe rule that a registered trademark has to be in genuine use. If it has not seen genuine use, it can be revoked (art 15 and 50 of Council Regulation (EC) No 40/94.
I suspect that is also the reason for the late C&D. This ground for revocation of a trademark can be repaired. However, there is usually a grace period (3 months for a Community Trademark, art. 50 CE 40/94). I would not be surprised to find that Psion started using the trademark again a little over three or six months ago. That would mean they had to wait until now to C&D without risk to their trademark.
NB: although I'm an IP lawyer in Europe, this is _not_ legal advise.
