Ok, it's only the beginning of summer. But pretty soon almost half the people will have smartphones and can make purchases on them. Mobile consumers will have the same shopping expectations as those online.
Keep in mind that a mobile store needs to be especially user-friendly. While using mobile devices, people are on the go, receiving and making calls, and are not really into surfing the web as much as they are using the device quickly to read something important or make a purchase.
You also will want to cross-link your mobile store and your web store. Sometimes people do want more information, but rather than imposing this on your mobile customers, let them link to your web site. Especially at holiday time, they may want more information, but you don't want to impose this on them.
