Check out this bad boy from Nokia I just read about:
That thing is pretty freakin' awesome looking. This was created in partnership with SEGA and runs on Symbian, according to this press release. Rocking. This was announced along with 7 other new models - one with a flip-over keyboard and a T68i killer 6100. Nokia took a while, but it looks like it's innovating and competing again. Good.
Ahh... It looks like there's also a Slashdot article on this and Here's an Business 2.0 article about Nokia innovation...
Now, how long before someone comes up with a WiFi, Bluetooth or GSM/GPRS adapter for the Gameboy?
