I know this is a typical question, but i need some advice on an upgrade... I currently have a 20" iMac G5 2Ghz which has gotten really slow over the past few years. It can't playback HD videos without lagging and converting videos from xvid/wmv to mp4 (to import into iTunes/iPhone/AppleTV) takes a long time. About 25 minutes for a 30 min show. I read that the newer Intel Macs with the Core 2 Duo processors can do this in around 5-10 minutes. So the question is, how much faster would the new iMac's be than the current MacBook PRO? I compared the specs and besides being able to upgrade to 2.8 Ghz, the CPU, RAM and GPU all seem to be about the same. If the iMac has a performance advantage over the MacBook Pro, then I'll get that. If the two are the same performance wise, then i think i would get the MacbookPro, so i would have both a desktop and laptop. Any advice is appreciated. Thanks.
