Thank you both for the help...I will wait until July.

I have a nook reader...for a long time...thought I'd plum worn it out...didn't work well...decided to buy another at B+N store in Fort Myers FL...had a deal...buy a nookHD+ and get a nook simple reader free! So I ponied up $270, and got them both. My first Tablet....then I found out no download from anyplace but B+N store.Did not like that...too confining...so I took them back. Now looking at the Nexus7....don't download much...can I get away with a16GB, or should I go to 32GB. Pretty big price uptick. I also note that Goggle/Asus may come out with a second edition in July...I don't need the 4G connection...all my work will be with WiFI. By the way, I worked on the old nook reader, and the silly thing is working fine...think it just wanted a short vacation.  Thanks for any info.
