I think the definition of "power user" still needs some work.
I could easily spend almost all of my spare time on my iPhone, mostly internet browsing and reading/posting on forums. But I don't, because I have Macs available at home and work and I want my phone to have a charge when calling or texting.
To me, a power user is one that knows the in's and out's of a device. Shortcuts, tools, workarounds, ways to make the device work for the user. Perhaps that's because I'm in front of a Mac all day and I'm paid to work quickly in a variety of graphic design applications. A power user will know all the little tricks to make short work of things.
But that's subjective too. Because I'm a power user compared to the average iPhone user. I don't need to ask questions about how to attach photos to text messages or save a photo to my camera roll and so forth. But compared to some of the devs in the jailbreak section I'm a complete moron and know nothing. SHSH blobs, basebands, stitching IPSW's…UGH! 😱
But…if we're going to stay with the definition of power user as someone who uses their device all day and has to recharge it periodically…I'm a power user.
