I am essentially looking for the BrowserLab of Devices. What would the normal process be for a big design agency to ensure that their websites look the same across a wide array of the standard devices? The Nexus, iPad 1,2 and 3, so on and so forth.
Edit: I was hoping for answers that didnt involve breaking the bank and buying every device under the sun.
Aside from testing on the physical devices, you could also test them using their respective SDKs and emulators, such as the Android Developer Tools. Even if you’re not using it to develop native apps, you could still create Android Virtual Machines (AVDs) and load the browser in them to see what it’d look like on that device.
