Hey everyone... I'm going to be purchasing a new imac fairly soon (probably around Christmas) and am looking at what would be the best option for me. I'm primarily going to use it for the internet, some photoshop/illustrator/dreamweaver stuff, itunes w/my ipod, probably a game or two (Does Sims 2 work on a mac platform?). Nothing really hardcore, no video stuff or anything like that. So here's my questions: Should I get the $1299 model or the $1499 model (I want the 17in screen)? I dont really know what I would use a DVD-R for and I'm not sure if that extra .2 of processor is worth it? What do you guys think? I'm thinking I will want to upgrade the memory to 512mb for $75. Will this be good for the programs I said I would be running? Or should I get more? Also, I've read of some people ordering memory elsewhere and putting it in their new imacs, does this void the apple warranty? Currently in my home we have wireless internet, all we have are PC's and they're all connected from a Linksys 802.11g router. Do I need to order an Airport Express card to be able to connect to this? Or is there a standard wireless card already in the imac? I think that's it for now, thank you for your help Allison.
