This deivce looks cool.  Looks kind of big though.  I'm wondering when they are going to be in the same unit though.  I thought I read somewhere that they can check glucose without blood, but I'm not sure.  Hmm seems to be some things out there like that...http://www.spectrx.com/cgms.asp. 

My dads is some what smaller.  I was amazed when I first saw his.  I thought he had permanent tubes or a needle constantly in his stomach.  But it is just a rubber hose that is in there, a needle like device shoots it into stomach.  Kinda weird.
