All-in-ones

I've been wanting to change my home PC for a long time (with all its crankiness and lug getting to me), probably by the next IT fair in June. And due to space constraints, Have been considering some 'All-In-One's and currently considering 2 soon-to-be-released models by Lenovo. Prices and models unavailable yet...seems like they'll probably be out in June.

IdeaCentre A320:

IdeaCentre B320:

Their specs are generally similar and well, it's a tough choice, although the 'B' might be a more high-end machine.

But then, yesterday I read the release of the new iMac which has tempting specs that seem to have comparable specs (if not better, at least for graphics and maybe speed) and can be custom-configured. And the price might not be too far off, starting at S$1,648 (but the leaps up are big).

As usual, Apple design wins hands down. The issue now is, do I want to give up Windows OS at home?
