B. Diddy:
Thanks again for your timely replies - I'll investigate those Groupon deals you suggested.
Since this is my first tablet I don't want to kick myself for purchasing Nexus7-look-alikes that don't measure up. I've read so many good reviews about the Nexus7 that I'm ready to just close my eyes and swipe my card already. By "upgrade features", I meant assuming Nexus offers it, should I get the most storage (since there is no expandable slot), fastest processor, etc... for it? I haven't seen where it's customizable so this may be a moot point.
One last question, since I have no cell phone, assuming I'm in a public WiFi hotspot, is it possible to use the Google Voice feature in GMail to make phone calls (like I can from my desktop) ?
Thanks for all your help and followup!
Dan
