First there were big screens. Then big flat screens. Now there are big flat screens packed with tricks, like the ability to record TV or access your home network. It’s all part of the push to minimize the number of decor-busting black boxes while maximizing entertainment choices—movies, slideshows, your music collection. Here are five reasons to chuck your TV in favor of a multitalented model.

1. The Laptop Impersonator
This 2.7-inch-thin flat screen takes its cue from the computer world, with two PC-card slots to handle its latest features.

In the evolution of ride-over-anything mountain bikes, the ever-vulnerable rear derailleur—that gangly parallelogram that shifts the chain up and down the rear cogs when it´s not clogged with mud or bent by rocks—has been a glaring technical handicap. So GT (gtbicycles.com) got rid of it. With its $5,000 IT-1, GT moves gear-changing duties to an unsullied haven inside the bike frame, by way of an eight-speed internal transmission.

Since the dawn of wireless, the roving Google junkie has faced two options: a bulky wireless laptop or a Web-page-cropping PDA. This fall, however, Nokia (nokia.com) will introduce a palm-size Internet gadget that surfs Web pages in full, albeit scaled-down, glory, anywhere. Measuring three by six inches, the 770 connects to the Internet via Wi-Fi or a Bluetooth cellphone. Think of it as a $350 replacement for that second PC.

Pint-size cars are the practical option in European cities, whose streets seem to be designed for wheelbarrows, but they come up short on safety. Keenly aware of this dilemma, Milan-based automotive designer Pininfarina has reconsidered subcompact safety from the inside out with its Nido concept car. Named after the Italian word for â€nest,†Nido refers to the unique design for protecting passengers of this diminutive two-seater (it´s 2.5 feet shorter than a Mini Cooper).
