hi guys, i just noticed a new model, just fyi 
http://www.drobo.com/storage-products/5C/
I just noticed the 5C at Amazon today! Had I paid more attention I would have grabbed a Gen 3 4-bay at closeout prices (assuming there were any). My last Gen 3 was $249.
thats pretty neat macgui, i got a gen2 from amazon i think for about 200 (pounds) which came with a droboshare years ago.
