I quite like iPhoto but it's far from perfect and Apple could do with the competition. I've used this a few times on Windows but not enough to really say if its for me or not. So will I try it - hell yes.
 
Eh... A little too late to the game for me. I will stick with Aperture and my website now.

It was nice when I was on my Windows computer, but I have since moved on.

If one is really using and benefiting from Aperture, I can't think of why in their right mind they would use Picasa... :p

Picasa from what I saw on PCs... It had a couple of minor niceties. In particular, on comparable era computers (I guess this is less of an issue now, with how fast the Core 2 processors are) Picasa seemed to get much less bogged down by having lots and lots of large images in it than iPhoto did. On a G5, I thought iPhoto was unreasonably slow considering what it was being asked to do.

Then again, over time, I stopped carefully albuming photos and just dumped them into iPhoto when I synced my cameras, for storage. Now on a PC, I, embarrassingly, just dump them into a folder (and use Paint.NET for photo editing). I probably should install Picasa on my Windows PC.
 
EDIT: Wow, I installed Picasa on XP/SP3 on my Eee Box (1.6GHz Atom N270) and it's amazing how much faster it is than iPhoto on my iMac G5....

It is a little quirky, though, in that it went and imported some kind of random image files from here and there in My Documents (like old image files for a Java game project I did seven years ago that somehow migrated with my Documents from my old Windows 98 computer to my iBook to my iMac to my EeeBox.
 
Picasa was cool, back when I had a pc. At the time I wanted to have it on my mac, but I gave up on it. Now I use Lightroom, so Picasa will be of no use to me.

That said, I take my photography somewhat seriously, for the more casual user, Picasa will be a great alternative to iphoto.
