Yeah but what I meant was is it worth the extra money as it will cost what? £329 at the current offer plus £109 for the cover 2, so £438. Is it worth it for almost £200 more?
You're not going to like the answer but the only person who can tell for sure is you, I'd recommend you get the 2 but you may find the first is good enough for you.
You could save a few quid by getting a second hand keyboard though.
