My assessment for the BDP-83:

Prior to Blu-Ray I wouldn’t get a DVD Player unless it had been loaded with options, easy to try, had an excellent reputation and was region free. Of all of the players I checked out this was the most effective one I could find and I have not been disappointed. It’s impossible for me to elaborate on each of the best features but I’ll say that it had been also very easy to change the player to try out discs from all around the world.

It is very unlikely that home theater technology will advance again any time soon and this is a player that is a great addition and will last for a long time.

With the iPhone finally coming to Verizon Wireless, the competition continues between the three hi tech phone brands. Which smart phone is right for you? Read our smart phone reviews below to find out.

Blackberry is the best choice for business professionals. Email is delivered seamlessly, and the Blackberry OS handles multiple email accounts better than the competition. However, Blackberry falls short when it comes to apps and web browsing. And if you are looking for 4g service, forget it. Rumor has it that a Blackberry 4g will be launched in June 2011, but for the time being, it’s 3g all the way.

Droid phones have a faithful following for good reason – they do lots of things very well. Droid users praise the thousands of free apps available to them, thanks to the open Android OS. The Droid Incredible is just one of many Droid phones that users love; it has an 8 megapixel camera, built-in FM tuner, and responsive touch screen. While the free apps and high tech features are impressive, some users find that email delivery is sometimes spotty, and call quality isn’t perfect.

The iPhone continues to dominate the smart phone market. It’s sleek, powerful, and user-friendly. And of course, it’s an Apple product, and Apple users are loyal through and through. iPhone users have access to the largest app market, and with the iPhone 4 operating on a 4g network, it’s a fun to use. The one major con for the iPhone, however, is dropped calls. Apple claims to have fixed this bug in newer models, but users still complain of repeated dropped calls.

Figuring out what phone is for you also involves determining which cellular provider you want your service through. Most providers will give you a discount on the cost of the phone if you sign a multi-year contract with them. Once you pick the smart phone that’s right for you, it’s time to deck it out in the latest accessories. Countless different screen protectors, cases, sleeves, earphones, car chargers, and more are available so you can customize your phone to make it completely unique. Accessories are available through online and brick-and-mortar retailers.

With all the smart phones available in today’s competitive market, there’s sure to be a smart phone that fits you perfectly.
