For those with Android you should buy a cheap iOS device if you have enough coins to make it worthwhile which will be most of the ICO investors. IF you stubbornly insist on waiting for airdrops you might actually shot yourself in the foot. A long delay and other competitors come into the space etc is far worse than you not getting airdrops. And like I said if you have a decent investment buying an iOS device is worth it. Don't forget if you are an early investor you can get friends assigned to your account and so the benefit of connecting with friends who have Android is also limited.
I know what you mean, but what do you do when 95% of your friends/colleagues have Android, because your friends/colleagues believe in Open-Source over closed-source?
(an AVERAGE of 80% Android-market-share for the HOLE population is not uncommon in many parts of Europe like in Germany -> if you are a tech-affine person, the share of Android is higher)
Maybe a solution would be to release the Android-App with an even more basic-feature-set than iOS
That's my situation too. But as early investors it's not as much a deal breaker as you think. Let's put the airdrop into perpective. let's say in quite a short time we have 25,000 users, then an airdrop IF your lucky will get you 1 GEM (on average) so the bigger picture for us as early investors is to make the app a success. Delaying the fully functioning app MIGHT be detrimental to the project, that's a call the developers and the community need to balance and make a decision on.
This is my hunch, if there is a long wait for Android the momentum will disipate, the price will drop and even froends you invited on IOS will wonder why you are excited about a chat app that doesn't even send photos. Without the gems airdrop you may as well not even release the iOS!
