I think it's not too uncommon -- I carry an iPhone 5s and Nexus 5 (in the same pocket), and I see a lot of other people do it too. I do it because: a.) iPhone OS is better but overall, but the tiny screen is super super annoying for many things (IMO) b.) this way I have NTT Docomo in addition to Softbank, so I get coverage underground and weird places where one or the other doesn't work c.) voice dictation is 100x better on Android, so I use the nexus for dictating things
