If you go to the bottom of the page and select "Change location", you might find that it's available in your country. I can pre-order for the UK (however unfortunately it's £49.99, a fair bit pricier than $49.99).
I've also just found that Currys (our last major high street electrical/electronics retailer that isn't part of a department store and is ubiquitous in most cities) has it available for next day delivery - http://www.currys.co.uk/gbuk/computing-accessories/accessori... - only the white version, sadly, and it's also £49.99.
Edit: Also, when pre-ordering on the Logitech UK website, it asks me to select my layout and color.UK layout is available (thankfully - a lot of Logitech portable Bluetooth keyboards available on Amazon are US layout only).
For most users the changes aren't too troublesome (see http://en.wikipedia.org/wiki/British_and_American_keyboards) but I'm so used to coding on on the UK one I find it difficult to switch. The \, #, " and £ are the ones that cause my most difficulty. And to me, the little US enter key just strange (it's double-height on UK keyboards).
Yeah, I'm both a Linux user/enthusiast (I need `~\|# in the Right™ places) and a developer (Switched from DE to US mostly for []{};: etc - the UK difference would be smaller here: A moved \ and @" would be most annoying).
The tiny enter key is actually a requirement for me (to have \| in the right place). Hrm. So maybe I'll shoot one of these keyboards with the US layout on eBay in the future or something.
