i can't post links yet but the website can be found by google searching "shop portenzo" .... till then
i received my Portenzo case a few days ago and love it. I got the case that holds a stylus. ( I use NoteTakerHD and iAnnotate a lot)
the case looks very professional and so far at every meeting I've been at the coversations aren't just about how am I using the ipad but where did I get that case.
I emailed Portenzo and they where even able to embose (spelling) our company logo on the case. For our iPad distribution in our company it has been a hands down Portenzo vote.
