Hi guys this is my first post, im soon converting from the dark ages, and buying a beautiful Mac. I have finally decided to buy decent hardware to make my life easier.anyways straight to the questions. 1.I have noticed that all iMac's come with a standard 256mb of ram, is that enough for me? basically what i want to do with the computer is make some pretty basic video's and music. midi keyboards and synth's. 2.Should i wait for os X tiger ? and then just purchase my computer then ? 3. is it easy to use external hard drives on a mac? thanks guys. oh and by the way im on a computer at work right now that uses windows me...BOO!
