I can't fault this product. Well, actually I can, but only a bit. I have experienced the same glitch that others have in that after upgrading to Snow Leopard, Front Row movies play very jerky, and I've had to revert to using 'DVD Player', which is a minor inconvenience really. Other than that I think this package is fantastic value for money. When you consider what they charge for Microsoft Office and compare that with just iWork on it's own, I think it's a no-brainer.
Speaking of no-brainers, I am not an intensive spreadsheet user or document publisher, so don't need the depth and complexity that 'Word' brings. And explains why I always had such trouble producing Word documents which were anything above very basic. I am self-employed and run my own advertising, website, accounts and marketing all using the suite contained in this box, and I am more productive, better organised, happier and less stressed than ever I was trying to use MS Office. Time saved alone is worth the investment.
One slight niggle again is the facial recognition software of iPhoto. It barely works to be honest. My suspicion is that it will work fine if you are starting a photo library from scratch with it. I had over 2,000 photos, and as it has to search and compare every single one, it takes a long time and can be quite inaccurate (I can understand it thinking statues are faces, but plant pots?).
Overall, a brilliant package of software, quite underpriced if you consider what is actually in the box and possible with it all once installed. Worth the upgrade!
