I can relate to this a lot.
I pre-ordered a new tablet that looked really cool in the kickstarter campaign of the StartUp that was building it. I was really hyped and thought the technology was awesome.

However, it took more than half a year before the kickstarter ended, the production was finished, and mine was ready to be shipped. In the meantime, the enthusiasm had more or less died as I knew I was getting it for so long. Result? I haven't even opened it yet despite getting it two weeks ago!
