i have never paid for online.
but aion it's tempting! oh god.
oh yeah, PS3 also have playtv, my country it's moving to DVB-T
for those comparing XMB to XNE, XMB won a emmy for user interface. it's fast easy .
XNE it's cluster of menu, plastically a inverted axis XMB.
ps3 inferiority is minimal and 2 main features lacking are already announced for next firmwares.
so in the end it's all up for personal opinion of what you like more.
even so i never would pay for xboxlive or similar service, when there is another doing the same for free.
