So then none of us expect to get our macbook airs to render 12 hour long HD movies in final cut pro while we are working with CS3 is running in a different space! But a lot of us do like to use iLife! I will be buying a macbook air in the next few weeks at the latest and am wondering what sort of performance to expect from the basic applications, iWeb and Garageband are what i mainly use to run a website and create a podcast series with episodes around !5 minutes long, normally i have itunes open in space 3 and iCal open in space 2 whenever the computer is on, i was just interested to know if i am likely to notice any slower responses or lower performance, longer load times than i do now, i have been using a 2Ghz core 2 Mac mini and a 20 inch imac up until now. It would also be good to hear of any none youtube or flash video performance issues or indeed the most apps you have run without seeing any slow down etc. Thanks to anyone who replies, i look forward to being able to join in the fun when my unit arrives!
