Upon further investigation, Browserola is not very interesting. For one thing, you can't put in a URL to test -- just a file. So, if your pages are dynamically generated, you'd have to load them in your browser, save the file, and then load it in Browserola. I won't even get into the complications this causes when you're dynamically generating different versions for different browsers. Secondly, it doesn't emulate other platforms, just other browsers. Seeing what your page looks like in other browsers in Windows is relatively easy (if you don't want to install those other browsers, why would you want to install a browser emulator -- why can't this run as a web app?). Across platforms is what you'd want an emulator for. I lost interest before I got around to seeing if the thing actually does what it advertises.

On a side note, why is the default folder for most software (installed on Windows, anyway), Program Files\Software Company Name\Software Name? It's like they all have delusions that: a) You classify software by who makes it. b) That you're going to be using so many different programs from them, you'll want a folder dedicated to their software. Stop this please.
