Even if Gaeilge was the only language I was going to work in, I would use the US – International keyboard for Windows rather than the Irish one. It is much easier to type a fada with it. (Just the apostrophe key followed by the letter.) With the Irish keyboard layout you have to type and hold the right Alt key, then the letter or the apostrophe and then the letter.
No patriotism involved. I just like things to be as simple as possible!
