Stupid thing about the whole situation, with not just m$ but sony and friends, is that the tech has come along so that u can buy a usb drive and plug it in - and away you go.
There`s the theory - and it sounds marvellous.
But no, hardware console/pc manufacturers seem to go out of their way to stop this.
Want a keyboard for your ps3 ? Should be able to pick up any1 and just plug it in. Want to use a mouse on ur 360 ? Should be able to plug any ole £2.00 usb mouse in and away u go.
No no, block it, prevent it, can`t have that. Here`s our m$ mouse rrp £30.00. Here`s our Sony keyboard £50.00.
