minikeys: how small are they?

[King Ben]

How small are the keys on midi controllers and keyboards with "mini keys" (for example the korg microkey or the akai lpk 25)
I am trying to decide if I should buy the korg microkey and I am wondering: do the small keys make it difficult to play the keyboard?

They're fine for little single line riffs or holding down a chord, you'll get used to them.

Not great if you're mostly a two handed piano/organ/synth player.

Thanks, that is very helpful. I have one other question: what are the actual dimensions of the keys?
