HDTV's: In the store vs at home

In a store, flat panel TVs are usually not placed very well. They're placed at different heights to accomodate more in a given display space; which means that some sets have an unfair advantage (owing to varying viewing angles). Secondly, many of them are set to 'store mode' which displays unnatural colors and brightness. Finally, don't trust the articially generated HD content they play; trust your own content (on DVD's or on USB drives) before making a decision.

Internet on your TV

If you have a HD flat panel TV, you can use it to browse the internet in HD using a laptop or desktop connected via HDMI. But since the standard browser is not optimized for TV use, you may have to squint a fair bit. Instead, use Kylo, a web browser specifically designed for this purpose. Not only are all the fonts and buttons larger, you also get a large address bar and easy navigation shortcuts.
