25. The UMPC (2006-?)

Originally hatched by Microsoft, Intel, Samsung, and other companies under the codename "Project Origami," the Ultra-Mobile PC made its way into the consumer's conscience in 2006. The devices were cool on the surface, but the concept was flawed from the outset because they just weren't that good and cost too much. The UMPC is the classic case of a tweener device (in terms of size) that just didn't have a real target market. Smarter smartphones like the new iPhone 3GS and cheaper but more usable Netbooks cut the legs out from under the UMPC before it could ever start walking. They're still around, but we expect them to become extinct soon.
