NEW YORK ( TheStreet) -- For many, it's difficult to go a day without checking Facebook ( FB) or reading the latest posts on a favorite blog or pinning a cool picture. Today, losing your smartphone is just as bad as losing your car keys.It was pretty much the same a decade ago. Only the names have changed. We checked AOL ( AOL), read the newspaper, emailed photos and lost cellphones. Many products and companies we once relied on daily have pretty much vanished (also see Life-Changing Tech's Fall From Glory). Some, like Apple ( AAPL), Google ( GOOG) and Amazon.com ( AMZN) continue to grab our attention and have us wanting to try something new. Others are waiting to emerge. So who or what is leading the way? That, of course, is anyone's educated guess. But here are some companies and markets to remember.
