While I'm guessing I'm going to see a lot of hate after I say this but I'm going ahead anyways.
A tech screw up that could have been on the list I feel is the Macbook Pro with Retina. Its one of those products that sounds great on paper but now that people are starting to use it and spec it, it's starting to sound like a screw up more then anything.
Reviews like this one are stating that the systems are having problems with viewing websites like facebook and are having an average frame rate of 20, with the new OS upgrade bumping it up to 20-30 FPS. This just came out and it's already having issues with keeping up with website scrolling? And on top it won't be upgraded for a year.
Its one of those tech ideas that sounded great, but didn't work out as well as planned.
