irish keyboard layout

Yow fellows,
i am planning to buy a notebook and found a notebook which perfectly fits to my requirements. the only prob is, its from ireland...so ofc its with an irish keyboard...
so my question is:
what are the biggest differences between the german and irish keyboard...
anyone got a pic or smth?

(ofc i could buy this notebook with a german keyboard layout aswell, but its cheaper with this irish one)

thx :)
