Well then it was an utterly useless point to make then as the solution to no sd card slots INCLUDING the iPad is not extreme data charges from mobile carriers but free wifi hotspots.
Unless you really do have more money then sense?
You're talking in circles. iPad at least has 16/32/64gb offerings and 4G/LTE radios in other models. That's why in my opinion makes the iPad an actual full fledged tablet and the Nexus 7 closer to a toy for browsing the web and streaming content...where you have wifi.
My argument wasn't to rationalize microSD or No microSD. My point is 8GB is not very much storage and as this is pushing you towards mostly streaming and cloud services, there should be another way to access that. If you wandered out further then your neighborhood McDonalds or Starbucks WiFi is not usually a free commodity. If you go on a week long trip and bring your tablet for entertainment hotels can charge $14.99 or so a night for Internet. If you're there for 4 days you've already spent more then a Verizon/AT&T/Sprint data plan for tablets for an entire month. Not to mention it doesn't have to constantly be active. It's month by month
So short version maybe you'll understand.
Low storage and no wifi access for cloud = bad for travel
Low storage and Cellular access when there is no wifi = good
