Watch out, Apple. HP on Wednesday introduced a new generation of premium computer products that could generate the kind of excitement in the market that's usually the domain of the folks at One Infinite Loop. Among the new HP offerings are a new tablet-laptop convertable, a svelte laptop, an innovative all-in-one model, and a 4k display designed for dual screen setups. "HP has absolutely raised their bar in design, quality and performance," said Patrick Moorhead, principal analyst at Moor Insights and Strategy.
