The Belkin Wireless G Plus MIMO Notebook Card can't compete with another member of Belkin's wireless-adapter family, the Pre-N PC Card, but it compares decently with other pre-802.11n/MIMO adapters and kills the plain 11g competition.
The Belkin N1 adapter is a little better than the competition, but that's not saying much. Hold off on buying Draft N networking equipment for now.
The Belkin Network USB Hub provides a simple way for multiple users to share USB devices wirelessly. It's a must for any multiuser household.
