I wrote a quick post about it on my DocuBlog, but hands-on feedback that I can write about would be a plus!
I have 20+ units in the field and they all work great. There was some minor introductory problems but new firmware fixed most of that.
I have one e477s black only version that is averaging 45k print per month for four months since install. The business plans to close down the end of March. It has not blown up yet!
Now the biggest problems is getting enough inventory all the way from Singapore.
