I have an iPhone 5, and I can personally attest that it is crazy faster than the old iPhone 4 I upgraded from. Once you add in 4G, LTE, and 5 GHz WiFi support, it’s so fast that – except for the obvious size limitations of a smaller screen – I find myself not even caring that much if I get the “mobile” version of websites any more. Even before the speed, I noticed the dramatically improved display. AnandTech says that if the iPhone 5 display was a desktop monitor, it would be the best one they had ever tested. Our phones are now so damn fast and capable as personal computers that I’m starting to wonder why I don’t just use the thing I always have in my pocket as my “laptop”, plugging it into a keyboard and display as necessary.
So maybe MG Siegler is right. The PC is over … at least in the form that we knew it. We no longer need giant honking laptop and desktop form factors for computers any more than we need entire rooms and floors of a building to house mainframes and minicomputers.
They’re both right and wrong. Yes, we can do sophisticated tasks on our phones, and yes, my iPhone and iPad have become technologies which I use for browsing photos, sending email, checking out blogs. But the desktop remains the core for something that I can’t do on an iPad or iPhone: photo editing. Even as mobile versions of Photoshop and other photo software products exist, they pale in comparison to being able to edit images on the big screen (I have a 27 inch iMac). I am still waiting for the retina display iMac, one that will allow me to see the 5,616 × 3,744 resolution images coming from my Canon 5D Mark II without downsizing. I believe we’ll be there in one to two years.
