I was looking for a nice way to check domain availability on my mobile but couldn't find one that did exactly what I wanted, so I made this little site: http://mobodom.com It should look good on mobiles, tablets and desktops in any orientation - as I've tested it on everything I could get my hands on. It does the job and it's quick, and I make no money from it's use! Interested to see what you think of it, or if you have any problems with it or suggestions. Let me know!
