I am setting up a new (larger) office for my company and decided to jettison the two PCs and replace with an iMac 27 and two iMac 21.5s - so far they have all been great. The 27 is ridiculously huge (not really) and the 21.5s are sweet as candy. All three are going to be kick a^%$ machines for what we do - which is lots of cloud computing based spreadsheets with large amounts of scrollable tabular data. The magic mouse combined with the large screen real estate is going to be awesome.
