Have a look at a Nexus7 tablet with Skydemon instead, it will download your NOTAMs, weather, AIP airfield plates and information, has a nice moving map display with NOTAMs graphically overlaid, allows filing flight plans and GARs. The Nexus7 comes with a built-in GPS. Oh yes, you can send emails, browse internet and view Youtube movies as well.
I find the 7" tablet just the right size for cockpit use; use it as a kneeboard.
