Mac OS X Version 10.5.4 Leopard

First let me say that my iMac 20" was only my second ever apple purchase. I'm a former PC gamer and hardcore PC guy who has given up on Microsoft.

I've used everything from FreeBSD & Linux to Windows XP/Vista and this is the most stable consumer based operating system. The OS loads very quick and the integration with iTunes & Safari is wonderful.

I have a brand new imac to replace a G4 that I really liked. Leopard is so bad, installation was a nightmare, it still crashes all the time and nothing is compatible. There is no way I would recommend a Mac to anyone, and I used to all the time. I can only hope they improve it because Leopard blows. Boo!

I've been a Mac user since the late 80's and I swore back then that I would never own anything else (I currently use the MacBook Pro, and still have my SE, iMac, iBook, and 1st gen iPod). I read the mixed reviews of Leopard, and was reluctant to upgrade at first. But I'm happy to report that Apple has not let its faithful long-time users down, by once again giving us the quality technology that we've come to expect. From standard features like the clean, user-friendly interface to new additions like Quick Look and Time Machine (I've been waiting for YEARS for Apple to supply its own back up program), Leopard 10.5 is a top notch product. If I had one criticism to offer it would be that Apple should have given us this product a long time ago.

I pre-ordered Leopard and upgraded both my macbok and iMac with it. The improvements over an already solid and stable os make this a winner in my book. Of all of the changes, the one I ask myself how I lived without before is quick look. As a graphic designer, it has served me very well. On my work computer, we use tiger and everytime I want to look at a file, I have to open it in preview or photoshop. Quick Look would be so handy in this case, and especially when there are multiple copies of a file with changes that you just want to look through quickly. I'm also loving the simple backups through Time Machine, Spaces gets a lot of use on my laptop and screen sharing in iChat is a godsend for my new switcher brother, who I screenshare over iChat with to troubleshoot problems or just to show him how to use an app.

It doesn't seem a whole lot different from 10.4--but overall runs well.
The printed manual wasn't much help.
