I'm a previous owner of the 27" iMac. I loved the machine, except for one annoying problem, the resolution. On the iPhone and the iPad, when Apple improved the resolution drastically, the "physical" size of the different objects no the screen remained exactly the same as before. Nothing has changed, even inside applications, you see everything exactly in the same size, just sharper and smoother. On the mac, however, it's different. When the resolution is higher, everything becomes smaller. Microsoft tried to solve the problem, semi-successfully, with the dpi settings. The Mac doesn't even have that option. You have to try and change settings inside applications in order to view text comfortably, and even that didn't work all the time. Why is that? Why can't they do whatever trick they do in iOS, with OSX? Is there any way to bypass that problem?
