I agree with the conclusion, at least part of it. Sony must offer better differentiation against competitors, in particular Samsung. HTC, gorgeous hardware and all, is still facing a tough time to sell lots of devices. Sony is in a similar position where hardware is really nice but software is usually lagging behind from the get go, let alone when devices are months or over a year old. My suggestion to all Android third parties: always offer the option of Google Play editions with only very light modifications and additions where there's added value. Skinning for the sake of skinning harms experience in the long term.
