Query: Installation a breeze on vista 32 bit, works great

Prompt delivery from Amazon - 2 day service! Installation a breeze on Vista 32 bit. Form factor combining mini-keyboard and trackball/ mouse just great. No problems working from 12+ feet. Had a miserable experience using HP wireless kb and mouse combo. How did I decide on Adesso wkb - 3000UB? Amazon reviews - thanks guys.One issue with kb. It is difficult to establish 'num' lock status. Hence 4 stars. 'Caps' status no issue.
