Reasons are irrelevant to those who want or need such services. The simple fact is, device A provides feature X, device B does not. Users have two options: get device A or manage without feature X. My preferred choice is the latter but I can hardly blame youmeego and others who go for the former.

If you are the supplier of device B and want to attract customers who want or need feature X, it is your job to make sure your device provides it. Otherwise you lose those customers. Simples. Blaming the provider of feature X is nothing but excuses.
