I just had to take over yet another person's itunes account this morning because they signed up using essentially my gmail address but with a period in it somewhere.

I don't know where the trend to no longer validate email addresses came from, but it's made my life hell because I was able to get a firstname@gmail.com address while gmail was in beta.

I'm looking forward to trying out the android version when you have it available.

It would be interesting to see what the subscription stats look like after a day/week.
