17 Windows browsers on your Mac. Sort of.

I've noticed it in myself (and I'm sure it applies to others) that I sense more "value" in downloading a "free app" versus using a free Web service. I was familiar with Litmus's services before, but I hadn't really bothered to give it a go until this. This desktop app makes it convenient (even though you have to use the Web to setup an account!) and it "feels" better somehow. If you have a Web app, think about whether a similar tactic could work for you (I've seen a similar thing happening with free iPhone apps promoting Web apps).
I think it taps in to old assumptions. "Software expensive, Web free." On 37signals Live yesterday David Heinemeier Hansson was talking about how people take recommendations more seriously when someone is a paying customer of something than just a free user. I think this sort of thinking ties in with software being perceived as more valuable and why Alkaline could, perhaps, get better buzz than the underlying service.
When I make a change in Textmate, I can cmd-tab into VMWare and refresh the browser in a couple seconds. I don't have to wait for the server to respond and download the images.
I'll stick with VirtualBox for now :) http://axod.net/browserTesting.png
You can download the XP images free from microsoft, ready installed with IE6 IE7 and IE8. You just have to jump a couple of hoops to get the images into a format virtualbox/vmware etc understand.
Where??
Currently time-limited to april 30, but so far MS continues to provide new versions. I guess they're just trying to prevent any other use of these images.
