(Hot Trends article updated with information on Amazon's new Kindle DX.)

NEW YORK ( TheStreet) -- Amazon's ( AMZN) Kindle DX is among the most searched for topics on the internet today. Amazon will begin shipping the upgraded Kindle DX, which will come at a reduced price of $349 compared with the original's $489 price tag, tomorrow.

The company says the Kindle DX has 50 percent improved contrast and darker fonts.

However, none of this may make for faster reading. According to CNN, a recent study shows that reading a book on a device such as the Kindle or the Apple ( AAPL) iPad actually takes longer than it does on a standard printed book.

The federal government's USA.gov Web site has launched its own app store with close to 20 mobile applications.

The apps include a product recall app, a White House app that provides users with up-to-date news and information from the White House, a "My TSA" app, providing travel alerts and other information from the Transportation Security Administration and even an alternative fuel locator app.

"USA.gov is working hard to make government easy, convenient, and accessible," reads the FAQ section of the USA.gov app store.

Some apps carry a small fee, but most are free.

Tar balls from the BP ( BP) oil spill in the Gulf of Mexico have started washing up onto Texas shores. Crude oil has now reached the shores of every U.S. state on the Gulf of Mexico.

While the number of tar balls that have reached Texas' shores is tiny compared with the amount of oil that has coated other Gulf state beaches, pollution remains a significant concern and those in impacted areas want BP to pay.

"Any Texas shores impacted by the Deepwater spill will be cleaned up quickly and BP will be picking up the tab," said Texas Land Commissioner Jerry Patterson in a news release.

"Smartphones" is one of the most searched words today on Google. Companies such as Apple ( AAPL), Google ( GOOG), Research in Motion ( RIMM) and Motorola ( MOT) are leading producers of these hot commodities, and continue to introduce new and improved models.

Recently, Nokia ( NOK) announced plans to sell its wireless modem business to Japan's Renesas Electronics for $200 million. Meanwhile, last week Microsoft ( MSFT) pulled the plug on the KIN, their most recent smartphone offering, after unimpressive sales.
