I am going to buy an iMac 2.93 GHz 24in sometime this year and i was wondering if i should wait because i am hearing rumors that they will be changing the LCD screen to LED. I also heard about them changing the duo processor to a quad core. Also I wouldn't mind having Snow Leopard. Right now I am using a 5 year old dell with XP. It still runs pretty good, but there is no way i am moving to vista. So this will be my first mac and i am really excited, but i don't want to get angry if I get one now and they upgrade later in the year. One last question, can i always upgrade the RAM on the imac or no? I also just joined the forums today so hello everybody!
