Funny you should post this, but I ran into that scenario's dark side just this afternoon. Back when storage was more expensive than it is today I did as you suggested and downsampled all the 2 megapixel full-size jpegs from a 2001 visit to my best friend's place into 1024 pixel jpegs. The pictures in question were of his kitties romping in catnip. One of them recently passed away and I thought my friend would like to have those pics. Except they were now just at screen resolution with the originals long since lost and printing them out wouldn't have yielded great results. I was able to up-sample with Genuine Fractals with a little success but the results were less than pleasing.
My own photo collection sits on a Web-enabled NAS box with copies on two desktop machines and a Passport USB drive. It's sitting at a mere 64 GB for the moment, though I expect that to at least double later this year. I delete *nothing* and shoot RAW+JPEG now. When you can get a Terabyte hard drive for $50, what's the sense of being miserly with disk space?
