We don't really know how performance will be. I'm sure this will be great for Halo, OpenArena, PSx Emulation, Sid Meier's Pirates, Sid Meier's Railroads, Civilization 4, Dreamcast Emulation, and older games. Also the 10hours or more of battery life and the amazingly large high resolution make this perfect for VLC or other Media playback. This thing could could also be used for productivity through Openoffice.org. This would also be perfect for on the go voice over ip and video chatting. Th 5mp camera will be very useful for facebook and youtube. This thing has flash 10.1 so I can view websites other than youtube. This thing would also be great for managing and being used as a Linux LAMP server. Anyways I'm thrilled about this device. Also this is great because no more begging for promises that Nokia will never fulfill like Flash 10.1, various games, Meego upgrade and many of the other Nokia could have easily provided, but were too greedy to do so, instead I can install all of those things myself on the Ocs1. the Usb host functionality is something I wanted out of the n900 but it never got it. This has a REAL keyboard unlike most devices coming out these days.
