US Keyboard is about 99% similar to European (assuming QWERTY). Main difference is Cap 3 is a # sign (US still call that a Pound sign) and a few minor special characters are in different places such as the @ sign, the \ sign and some US keyboards don't have a EUR symbol.
Really minor differences -- just switch in Windows to the layout you want.
I usually with a laptop take a small portable Wireless Ms Arc keyboard -- when working in France or Belgium I just can't even THINK of using the AZERTY keyboard -- 5 mins on one of those and I'd just chuck the whole computer out of the window.
The keyboard is really light and when travelling the micro receiver is magnetically held under the keyboard so you don't lose it. Small battery lasts YEARS. I've only replaced one and I've had thekeyboard for at least 7 years. Lasts longer than the laptops I've used it with. !!
Here's a pic of EN (UK) version.
I use ISL keyboard -- works fine for English and has some umlauts too for writing German text when I need it. Plus it has ISL special characters --rather like Danish with some extra symbols.
