My HTC One X Plus takes a nano-SIM - it was a pre-release unit sent to journalists on loan.
I liked it, so I bought it at a discount. I realised when a colleague got a handset that there were differences.
I used to write for Mobile News, a fortnightly cellular trade weekly, here in the UK.
FYI there are two versions of the Samsung Galaxy SIII in circulation - one takes a mini-SIM, whilst the other takes a micro SIM
I also have a Star W007 dual SIM Android handset, but that's another story.
