5. Move Move around your stage. Start off in centre front and then move so you cover a lot of ground. Static presenters are not seen as authoritative.

6. Create powerful associations. Link yourself to other powerful and authoritative people by agreeing with what they say. Use quotations if necessary.

7. Be short and sweet Speak with short sentences and leave pauses for people to absorb what you have said. Long, convoluted language makes you appear unintelligible and therefore you have no power or influence.

8. Have a stunning opening Start with a dynamic and interesting opening that connects with your audience immediately. Mention them, use a personal anecdote or ask a question.

9. Power pack your ending Make sure your ending is power-packed. Like a great overture you need to end with a rousing crash! To do this, summarise what you have said and then give your audience an action you need them to take.

10. Stand still at end When you have delivered your final words – stand still, centre stage looking your audience in eye. Stay there and pause for several seconds before leaving stage.

In meantime, you have your choice of buying an HDTV "capable" "enabled" TV if you choose to buy a digital TV. An HDTV capable TV means that it can process digital signals (like DVDs) but in order to display high definition signal it will require you to purchase an additional tuner which you can buy later at any time. On other hand, HDTV enabled simply means that TV is fully capable of displaying high definition picture and sound right out of box. The choice is yours. Either bite bullet and get whole HDTV enabled enchilada now, or defer it a while longer until HDTV programming is more standard.

You also hear a lot about plasma and LCD screens these days. The screens we have been used to for years are called CRTs, and they have worked just fine, but main advantage of plasma and LCD screens are that they can be very thin to produce, usually they are only 2-3 inches wide and that makes them able to be mounted in many places that CRT screens just can't go. If you need that kind of screen, just bear in mind that plasma and LCD screens are still very expensive. There is nothing wrong with just getting a good CRT screen or a rear projection screen in meantime as they can be had for not a lot of money and can still produce a great picture depending on manufacturer.
