Here's the quick run down. We have an iMac G5 PowerPc that is five plus years old. It still runs fairly well with regards to web browsing, mail, photos, etc. It's no longer compatible with the iTouch or my iPad 2 which at this time is frustrating. With the advent of Cloud, will this remain an issue? Neither my wife or I do any intensive editing or photoshop. My son and daughter use the computer for some flash games that run rather slow, and they're slowly getting in to more school age curriculum (second and fourth grade). Or at least I hope they are! Videos still run ok, but not great. I use the iPad for 95 percent of what I do. I'm not exactly sure what I would use the new iMac for, other than some word processing, excel, email, photos, and iTunes. I'm trying to convince myself we need a new computer. I'm tired of looking at the washed out 17" matte screen. Programs need to be "force quit" more often than in the past. All that said, this dang iMac is built like a horse! It seem like most of you guys have a specific use for the reason for upgrading. I'm searching for mine......but it feels like time. Anyone in the same boat or have an opinion either way?
