I’ve always been a Mac fella. I’ve only owned one PC and the thing was such a pain to use I almost never touched the thing. The only problem I really hit with Macs is when I’m building web sites. On a Mac, if you don’t have VM Ware or Parallels or a PC kicking around (which I don’t any more) you don’t really know what your website is going to look liketo PC users. You could build out a great looking site only to find out that in IE6 and IE7 the layout completely breaks. I’ve tried using sites like Browser Shots but they have always been a pain. That’s where  Adobe Browserlab comes in. Not only can you tell what your site is going to look like on a PC, there are also other features like onion skinning that helps you see subtle spacing and font variations. I used Browserlabs while building Farmidable’s current layout and it was a dream come true. No more instant messaging friends on PCs asking them for screen shots or explanations on how the site looks.
