Blackberries
No, we’re not talking about the fruit, but rather the old-school cellphone. Blackberries earn a special place on this list because everybody wanted one after their initial release. They had more buttons than a haberdashery and appeared to be peak technology. But then smartphones came along and swept them into obscurity.

Suddenly, everyone realized that the only thing better than loads of buttons was no buttons. The problem was the iPhone because Blackberry didn’t take them seriously. This was a big mistake because iPhones are more fun than Blackberries. The business-oriented devices failed but they’re a reminder of the good old days (via The Guardian).
