I'm about to order a Macbook Pro with an English language keyboard but cannot decide between the two localizations available. Therefore I'd like to ask you to give me hints, pros and cons if you have used both or if you have some strong preferences.
The two localizations are:
US English:

International English:

The notable difference is that the International English localization has a reverse L shaped return key and an extra key next to the left shift making that a tiny one.
You should also know that I'm a non-native English writer and my native language -- Hungarian -- uses so many accents that that extra key on the Hungarian keyboard localization (which is exactly the same as the Intl one just with Hungarian accented chars) is used for a valid letter. Fortunately, when I'm writing code, I strongly prefer an English layout due to the alignment of the brackets and quotes, plus most of the time I'll write in English, not Hungarian (only to my mom or so). I guess I could create my own accented layout with Ukulele so that extra key is nothing too important.
How do you like the small reverse L shaped return key on the Intl English keyboard? Is it robust enough? Easily accessible? How is the left small shift key? How are these comparable to the larger brick shaped keys on the US English keyboard in terms of typing usability and accuracy? (Unfortunately I don't have so much access to English keyboards that I can spot typing differences.)
