Be aware, residence of the UK, that this is a US layout keyboard as I found out to my dismay. To use it properly you therefore have to alter your system settings to a US keyboard layout. This wouldn't be a problem if it wasn't for the lack of a pound sterling input on it. Or euros for that matter.
The keyboard itself is a bit awkward to use. The keys feel wobbly to type on, as you'll doubtless realise when you try to write something with it. And the backspace key is too small. I keep hitting the strangely placed '\' key. Finally the keys sometimes double tap. Writing this review I've had to make endless corrections, which is just so tedious.
Note that Vista does not recognise this as any kind of known device through the USB. You have to use the PS/2 adapter.
Pros:
Quiet, comfortable (ish), looks nice, it rolls up
Cons:
Key's sometimes double tap, feels wobbly, awkward to type on, US layout, small backspace key
My advice would be to go for a nice slimline logitech keyboard. This is more of a novelty than an actually useful product.
