The company I'm currently working with purchased 30+ mobile devices.

I'm getting more and more convinced that this is the only way to guarantee that your site/app will work perfectly on all of these phones and tablets.

Some emulators can be a pita to install (iOS emulator only works on OS X, windows phone emulator needs Visual Studio on Windows 8 on hardware that supports HyperV) and they're still not 100% consistent with what will happen on the real device.
