I have the S1 IS. All I can say is it's an incredible camera. It is usable by both the most inexperienced and most experienced photographers alike. The "auto" mode is fantastic and works in most situations. For those extremely special situations like photographing stars or something, special modes are available such as extended exposure, multiple frames, etc.
I mostly use auto. My friends are continually impressed by the quality of the pictures this thing takes.
Here's a link to one of the pics I took a couple weeks ago. Just used auto, press and click. Those that have taken sunset pictures with film know this is a difficult shot to get right:
Sunset picThe video modes are pretty impressive too. If you want a sample, just IM me and I'll send you one.
I'm sure the Minolta is a fine camera as well, but I can tell you for a fact you won't be disappointed with the S1 IS.
Best Buy has it on sale right now for $400. You'll probably want to spend another $100 for an extra memory card, a couple sets of NiMH batteries of the 2400 mAh variety, and a charger.
Good luck.
