I don't think Lionel has ignored 2/3rds of the market. I don't think they've ignored anyone really. They've made the specs available so others can make (and already have) available command control for Lionel on other platforms. They have provided it themselves for the platform they felt was most cost effective at the time they made the decision to deploy the system.
And I don't think it's just a little difficult. It's a cost issue. It would cost Lionel more to attempt to support the fragmentation in the Android market specifically and more than one platform (already settling on iOS) in general. And others are making Lionel's system accessible to Android such as BlueTrain (https://play.google.com/store/...m.phonegap.bluetrain) and eTrain mobile (https://play.google.com/store/...etraincommandmobilel) so it would appear Lionel's strategy is working. Why would they spend more R&D money to replicate what other's have already done or are willing to do? And if one becomes enough of a run away success, they could always acquire that entity as they did with IC Controls.
It's not just a hobby to them, it's a business.
