I just posted a first impressions article on the REDFLY Windows Mobile Smartphone Companion that you may enjoy reading. It is a very nice piece of hardware, but if it is priced at US$500 then it seems to lose much of its appeal. There is no OS on the device like the Palm Foleo had and it just extends your Windows Mobile device to a larger display and keyboard. I like the idea and would snap one up for US$200, but not at US$500.
I do have a photo of PocketBible with Maps running on the 8 inch display of the REDFLY so maybe this could be a good Bible study device to work with the powerful Bible applications available on Windows Mobile.
I also have another device that I have to keep secret for now, but check out my ZDNet site early next week for a HUGE review.
