I'd would feel much more so owning an Apple laptop. I feel lots of folks in B&N or Starbucks using it there just want to show it off. I doubt I would ever bring it there, most don't.
Do you have data to support that presumption? That they just want to show off? What makes you think that? Because they're using it in public? So MacBook users are showing off but the Asus users, well, they're just legitimately trying to get some work done?
I find your statement even more ridiculous than the OP's statement that using an iPad anywhere is showing off. No one is impressed by a MacBook or an iPad.
Just like Chupa said, 170 million iPads. MacBooks are one of the best-selling laptops these days. No one will be impressed (nor will they think you're showing off) by using your Apple product in public. 10 years ago, maybe. 2014? No way.
