It was only a month ago that Marks and Spencer became the first UK high street retailer to launch a fully comprehensive, commerce-based mobile site. Besides Amazon, most other retailers have focussed on apps, or nothing at all for their mobile offereing.
However a recent article about a discussion from 5 CIOs of retailers shows that they clearly understand the limit of apps (no one opens them) and that mobile require their own specific sites.
So, it looks like retailers will finally get on board this year and produce some decent, mobile focussed sites that actually allow us to buy stuff!
