Meet Ime (pronounced I-Me).
('scuse the mess, I was attempting to eat lunch whilst setting up)
I originally wanted the 27" version, as in my head, 27" was quite small, until I sat down in JB Hi-Fi in front of the 27" iMac and had to move my head to be able to look at all of the screen. So I decided to downgrade there and then to the top model 21.5". The husband was quite surprised when I said I brought the smaller version, as I had been harping on about NEEDING a 27" iMac since they were released.
