Re: What is/are the worst or most unbelievable plot convenience device
You're working under the assumption that the small device doesn't tap into a much bigger power source/infrastructure.
As far as things looking more advanced, I find it far less shocking a transition than TOS to TMP. Technology could have been moved ahead by scans of the Narada done by escaping Kelvin shuttle craft. Spock Prime was needed to make transwarp beaming possible.
What perplexes me is that fans give so many nonsensical things in the various series and movies a pass. But when Abrams does something, it becomes universe breaking.
The problem is we are talking an alternate timeline universe that's so much more advanced, for no apparent reason, than the TOS timeline, that you can beam great distances with, as one user put it, something Scotty can hold in his hands. Look at the side of the JJ Enterprise engine room. Look at the friggin' girth of the warp nacelles. They can't even power the ship or go to warp with anything that could be remotely held in your hands, but somehow a small magical McGuffin device can achieve what are far beyond simple suspecion of disbelief, it's more like "Are you fucking kidding me?"
