Of course you do, It was freaking sweet! Back in the day the handheld video game world was ruled by the Gameboy who's only limitation was the fact that it did not have a color screen. Sega decided it was time to release colored screen handheld device and started development on the Game Gear in 1989. The system made it's way into the US in 1992 and was a definite success, if only for a short while.
The major problem's with the game gear was that it was expensive to own and operate. Game Gear cost $149.99 compared to the Gameboys measly $89.99 price tag, but the Game Gear also require 6 AA batteries to work vs. the Gameboys battery requirement of 4 AA. Possibly the biggest reason why the Game Gear never over took the Nintendo Gameboy, was the lack of games; Sega never managed to get enough developers on board for the console.
It's a real shame that the Game Gear never reached (in my opinion) its full potential, although it did have some awesome accessories that you could buy, one of which was a TV tuner. Imagine today's technology with the unlimited access to endless media that we have, then think of yesterday's equipment where people were excited if a device was considered "Mobile". The ability to watch TV on a hand held device that also played video games must have been ridiculous.
On a final thought for this post, don't ever go into nostalgia mode when drunk, you might just go on eBay and start buying up all of this cool shit.
On one other final thought, I've decided to buy every video game console released in the US (from 1980 on [but also maybe even later than that]).
