We believe most small websites don't have sufficient traffic on mobiles to make use of the feature, while bigger accounts would have custom websites and landing pages for mobiles and tablets. Of course, we could have launched it for everyone but we have been trying to introduce some premium features without increasing our base pricing (our basic plan of $49 for 10,000 visitors hasn't changed in last 2.5 years since launch).

I guess it's always a tricky deciding which feature to apply to which plan.

On the flip side, since a lot of sites are now just starting to experiment with mobile commerce, mobile landing pages and such this feature might be useful as an acquisition "hook."

Yes, it was very tricky to decide whether to release for all or for selected plans or even introduce it as an addon. Ultimately, we decided it to launch for $249+/mo plans only.
