I guess I never tried to check out MacRumors in Best Buy. I imagine they don't want people just standing around and using their demo computers to go on sites and mess around. Their idea is to let you check out things like the keyboard, speed, ease of use - you know the features of the product. Not play around on the internet. Granted how fast a computer can load a site is a good thing to check. And while I can see the need to see GPU performance with games, I don't think they can allow that for just a casual shopper. But obviously they permit more hands on than an online store does. And unless you have an authorized Apple store close - or Best Buy - you won't be getting a hands on of any macs at an online.
I admit to using my iPhone to price check so I am very glad stores are not using jammers.
Just some observations. 😎
