@cubot - tried Arc Welder but it says it requires Chrome OS (which I do not have).
@mbaluta - thanks for the recommendation. I tend to prefer VMs over emulators due to past experience and trying to replicate as closely as possible what a user using the actual device would see. Won't rule it out though. Great tip about Opera 12.16. I've installed it and already noted one thing I need to fix on our site!
