EDISON - It's tough to keep up with technology these days.

Each year something bigger and better or smaller and faster seems to make our current gadgets, a thing of the past.

Yahoo Shopping asked several analysts to offer their thoughts on gadgets that will be phased out over the next few years.

Analysts say by 2020 portable GPS devices, low-end digital cameras and DVD players could be out of date.

They say GPS and cameras could be replaced by smartphones, while DVDs will fall to streaming video services.
