Look's nice but really just overkill. You spend all that cash on this set up only to get owned in CS:Source/COD4 by some 13 year old with a £10 budget effort !
Touch late.. but aren't there USB screens already? besides my MP3 player has a wee colour screen, it charges od USB so might do the trick.. if it needs an AC cable thata a pitty, more cables... yey
Amazon had this up for pre-order in February, your mostly paying for the full color lcd this time around, fully usb2.0 ports and re-instatement of a line of G keys.
Considering the G15 MkI was £99.99 mrsp on release, £143 isn't bad from a Logitech pov.
From a gamers pov, that lcd has to be utilized by game companies to make it more than a gimmick. If it is, ur gonna be pretty tempted.
