I'm in my 60s and have used many computers in my time (IBM and Burroughs mainframes, CP/M desktop, IBM PC, etc). At present, I have a Dell on which I run SuSE Linux 10.1 and, under VMware, Windows XP. Microsoft's stealth 'updates' have worried me, while the most recent Linux versions seem full of bugs. I'm ripe for conversion to Mac but have some questions that I haven't seen answered elsewhere. My present thoughts are to get a 24" alu iMac and a MacBook as backup (in case of trouble). 1 Dell gives me on-site, next day servicing (needed it only once but it worked). How does Apple compare in the UK? 2 I've read that iPhoto '08 uses a single file to hold all your photos. That causes me some concern. What happens if the file is corrupted? Is there any way to save the photos outside iPhoto '08 for belt-and-braces backup? 3 The Apple description of Time Machine contains the following: 'Choose any date recorded in Time Machine to set up your new Mac exactly as your previous Mac was on that date.' Would that apply if my iMac failed and I wanted to work on the MacBook? 4 Is it wise to partition the hard disk in the iMac, separating OS & programs from data, as I do with Windows and Linux? Thank you in advance for reading this and for any help you are able and prepared to offer.
