I am sitting here at my iMAC - solar keyboard - wi-fi and behind me I have a sony notebook - loved my IBM computer steady and sure til a vendor decided to get inside of it via conference call and that was it -first mouse in 11 years - heard Apple was less prone to viruses so that is why I went that road - - it's the difference like eating at mom's diner - good home made food - or prime rib at that special place - both great - - as I said what initially switched me tho was from the virus aspect - I am retired and like desk tops -
