BIOS upgrade ?

Hi, I have a new UX21E -KX002V - Intel i5 2467M - 64Gb SATA 3 SSD - 4GB DDR3 1333
Win7 Home Premium 64 Bit. - BIOS V205 (the first one ?)

No special problems for the moment but at the ASUS support , I see the recent version is V210,
and there are some things that intrest me for an upgrade:
(in V207 : 'fixed system Intel Anti-Theft' ; I do suppose it works with the i5 core ?
and 'enable USB3.0 down mode' - 'update VBIOS ?'

Normally (or mostly) you can downgrade if everything is not working propely with a newer BIOS version.
Someone hints, experience with the newer version ?
