I've decided to make the switch and ordered a new 3Ghz 24" iMac. I chose a 1TB HD and 4G of RAM. I want to do some photo and video editing (nothing professional, simply vacation photos and video). Any suggestions on the following would be much appreciated: 1. Back-up: Should I use a 1GB Time Capsule or a 1 GB GTECH drive with Time Machine? 2. Should I partition the internal HD? 3. Should I use a 'scratch disk' for video editing? If so, any suggestions? 4. Any suggestions for ease of transfer of my data from my PC (photos, iTunes library, mail, IE favorites, etc.)? 5. Anything else you would suggest for a new Mac user? Thanks for the help and the incredible education I've received from these forums!
