I want to buy an MP4. I'm a high school student and I'll save money to buy it myself.

1. The screen size, most MP4s are 2.-2.6 inches, and it is not clear if it is smaller. If you watch cartoons or movies, the bigger the better, unless you believe in your own eyes or a foreign language. If you watch video (song mv), it is enough to buy 2. inches

2. Supporting formats, most of them are asf.wmv.avi. Now there is an rmvb player, at least 5 yuan, but what you buy depends on the use. If you watch animation or movies yourself, you'd better buy rmvb, because you don't need to transfer it. If you watch it online, buy one that can play flv format. If you watch video (song mv), buy avi and wmv.

3. Functions, what 3d games, e-books and radios can be directly proportional to the price and inversely proportional to the use.

4. Brands, big brands come up to thousands, and the things are the same, except the quality is different from the after-sales.

5. Capacity, the bigger, the more expensive, 2g is enough, and 4g is better. If you watch an animation or movie yourself, you'd better buy something above 4g, because it's too small to hold several episodes. (Of course, look at the battery. If you can watch the video for a few hours, of course, buy 4g. If you can keep it for 2 hours, 2g is enough. If it lasts for dozens of minutes, don't buy it. ) If you watch online videos, buy a 2g one. If you watch videos (songs mv), buy 1g, which is enough. < P > You can buy a very good one around 5-7.
