iHi! My sister is buying a new iMac, and she's relying on me to help her choose the right one for her.. but.. it's so difficult! I spend 10 minutes trying to decide which shoe to put on first! Initially, I recommended the lower 21.5", being the cheapest and totally fullfilling the needs of her family.. but then again.. that 27" sure is purdy.. and it's not really THAT much more expensive then the 21.5.. but it would be a total overkill.. but is that a bad thing? I mean, atleast the kids will get a healthy tan! The alternatives are: 21.5" lower (9500kr) - cheapest, but is 500gb and gfx good nuff? 21.5" higher (11500kr) - 1tb and better gfx, but is it worth 2000 more? 27" lower (13000kr) - now it's just 1500 more for the most kickass display ever! but is the gfx a bit weak for the bigger resolution? Does anyone have any insightful advice on how or what to choose?
