Hi Jordan,

was just skimming over it today. I think I'll change my mind 
and claim the opposite: great product. I wasn't aware there is
also a full release. Tomorrow I will have a closer look at this
product but it looks really impressing so far. Thanks for 

Hans :-)

What was missing from these emulators?  SimNow was designed specifically to
develop firmware images.  What did you find lacking?
