I use both my phone and by tablet. I do prefer the tablet for most stuff, but when out and about the phone is easier to use. I rarely use it to with a web browser, though. there are plenty of apps that pull info down off the web and serve it up better than a web browser. Using the apps for this forum on the phone works well, but whenever I can, I go to the tablet. The tablet is more useful for most of the stuff I do, except when I'm moving around. I especially prefer to use my tablet for navigation, but if I am out and about, then the phone provides a more quick and dirty option as I don't have to mount it. I don't make many calls on my phone...it is more like a pocket computer. I do think the article applies to me, though. I do feel a stronger connection to the tablet than the phone, but I have to admit I enjoy having both. And I like the fact that the iPad is pretty much a big iPhone or iPad Touch.
And I still use both a desktop and a laptop!
