I had a GREAT idea for new iMacs in the future: a built-in battery! Imagine this: the iMac with a battery would look just like the iMac today, except instead of connecting to the outlet through the outlet through a conventional thick white cord, it connects to the outlet through a charger cord not unlike the one used by a MBP or MBA: magnetic connection and all. The battery inside the iMac is not a large or particularly powerful battery... it can only power the machine for about 45 minutes on a full charge (longer in sleep mode, you get the picture). That would cut down on the price of the battery itself (hopefully). Now, what can you do with a 45 minute battery? Well, you can much more easily move the computer around. The iMac is an all-in-one design, and I find the machine is relatively easy to pick up and move around. This feature needs to be built upon! Why call someone over to your machine when you can just pick it up and take it directly to them? I dunno about you guys, but to me, that would be a great convenience. The battery would also come in use during a blackout. It would give you the time you needed to at least save your data or finish something up before you shut the computer down. Maybe I'm bonkers, but I think this would be a great innovation in the computing world. It would really make iMacs stand out from other desktops. And for that matter, it would eliminate my need to shut down my computer every time I want to move it more than 5 feet away from the nearest outlet. What do you think?
