Ok so I have used Macs before friends and at college. I am kind of tried of the usual PC giving out after about 2 years. I got a Dell 530 a year ago and dont doubt it still works great but I hardly use it and have been using a laptop more. I am thinking of getting an imac. Does anyone have any opnions on it they are really worth the extra $$? Are they truly better than a PC? Also I have found I can probably get a better deal on one from ebay. I have been trying to decide between the 21.5 or 27". I dont game - really just edit some personal pics, surf the web, listen to music, use itunes, etc. Also would have the computer in an extra sitting room/office and would be good for my wife and buds to watch DVDs on when my buds are gaming or watching sports. So any help, advice, etc would be great!!!
