From our perspective: yes. But legally and from the perspective or the mass-marketed users there really isn't much for them to think about or consider in terms of flexibility of application installation. (freedom is such a vague term to describe platform access - are you really free if you don't harvest your self-grown silicon chrystals, diffuse the chips yourself, write the firmware and OS yourself etc?)
Ironically, we could turn this on it's head: when the iPad came out people commented humorously "nobody asked for this" but apparently it was a device we didn't know we could use or enjoy. The same could be said for personal platform access. But what shape or benefit (and downsides) it gives to the mass market user eludes me so far.
The benefit of phones over laptops is the mobility, and I see no reason why the open options should go away for that mobility
