The trend towards people using smartphones and tablets to browse websites, and to make purchases, is accelerating. I reckon a lot of PCs will not get replaced over the next few years, so eCommerce websites should be designed with this in mind.

Whether you do it yourself or pay someone to do it, keeping the platform up-to-date to cope with the growth and variety of mobile platforms and different display areas is becoming a significant annual cost. Hosted platforms such as Shopify offer what appears to be a robust service, at quite a high price, but what is the real cost of a bespoke site and a good maintenance/upgrade contract? And what are the risks involved with the two approaches? Does anyone at EP have relevant experience?
