If you own ASUS' first full HD tablet - the Transformer Pad Infinity - the custom ROM scene just got quite a bit better for you. Why, you ask? Because the TF700T is now officially support by CyanogenMod, and the first CM10 nightly is already available.
Of course, in order to flash this you'll need to unlock the bootloader, which, in turn, voids the warranty.
It's also worth noting that once you abandon ASUS' stock firmware, there's currently no way to go back, despite the fact that ASUS makes the update blobs available (I learned this the hard way with the TF201).
