What about the Amazon Kindle3? Compared with kindle 4,5?

K3 is very good, and the comparison with the generation is as follows:

1. K3 has a large capacity of 4G, and K is 2G;

2. K3 has a long battery life, and it can be used for 28 hours when reading books, which is only half of it;

3. K5's screen 167

PPI has been optimized, which is better than K3, and the difference is not obvious in essence;

5. K3 is slightly larger than the size of the physical keyboard because of the physical keyboard. The smaller ones are more portable, but if you need to take notes, etc., a physical keyboard is much easier to use than a virtual keyboard.

The above is the comparison of the machine itself, you can choose according to your needs.

If you want to read a book, it's still kindle3It's a very good choice.,And its system is still linux.,It's very powerful.,Plus, kindle3It's the third generation.,The technology is very mature.,It's more famous.。

And the kindle33G you said is actually not very useful.,A lot of web pages can't be opened.,And it's like China's e-network speed is super slow.,There's not much need for this.。

Nook2 is still a certain distance from kindle3.

I recommend that you buy the kindle3, I've been thinking about it lately, and I'm also a person who likes to read.

1. The time to market is not the same

The Kindle 3 was released on August 27, 2010.

The Kindle 4 was launched at Amazon on September 28, 2011.

2. The appearance is not the same

The silver "kindle" logo on the Kindle 2 was changed to slightly concave black on the Kindle 3, and it was changed back to silver on the Kindle 4. The left and right bezels of the two are almost the same width, with the upper side of the Kindle 4 slightly wider than the Kindle 3 and the lower bezel slightly narrower, making the Kindle 4 a bit smaller overall.

3. The performance is not the same

The Kindle 4 has one more reading light than the Kindle 3, and when the brightness of the reading light is also set to 18, the Kindle 4 is slightly warmer than the Kindle 3, and when the brightness of the reading light is adjusted to the maximum, it can be seen that the backlight of the Kindle 4 is slightly more uniform than that of the Kindle 3.

4. The available space is not the same

The actual free space of the Kindle3 is (firmware-based;

The Kindle 4 is firmware-based.

Appearance. Judging from the appearance of Bixiao, the coloring of the kindle4 is gray and black, and the kindle3 will have two colors: graphite black and white. The width and thickness of the kindle4 are not much different from the kindle3, but in terms of length, the kindle4 is 1 inch shorter than the kindle3, about the length of centimeters, the difference is too small to talk about, but in terms of weight, kindle4 is still a lot lighter than kindle3.

The biggest difference between the Kindle4 and the Kindle3 in terms of appearance is that the Kindle3 retains a full keyboard, while the Kindle4 only retains a cross-keyboard and 4 simple buttons. This makes the Kindle4 a little cumbersome in taking notes and finding content.

screen. The Kindle4 has an improvement on the screen compared to the Kindle3. The Kindle4 uses a high-contrast e-ink display, which provides users with brighter, crisper text and ** display effects.

At the same time, E-Ink makes the Kindle 4 look like a real piece of paper when in use, and uses anti-glare technology to allow you to read freely even in bright light conditions.

on hardware. In addition to the missing manuscripts on the keyboard, the difference between the Kindle4 and the Kindle3 in hardware is that the Kindle4 does not have a speaker. Without a speaker, the Kindle4 is not able to read aloud and **search for the eye** function.

This leaves the user with one less choice when reading, which will have an impact on the user's user experience. At the same time, the Kindle 4 has a 50% reduction in power and memory. This makes the Kindle 4 only have about the actual memory that can be used, although it can hold up to 1400 books, but the memory is really not comparable to the Kindle 3's 4G memory.

The non-3G version of K3 is more expensive than K4 (key version) by 200 pieces, all with wifi Internet function, more than half of the memory, more than half of the power, the processor is a little worse, etc., in summary, the capacity and weight of K4 (key version) is a reduced version of K3, but K4 (key version) is reported that its Chinese support is not as good as K3, due to the simplified keyboard, typing is depressing. Other functions are almost the same,It depends on which aspect you focus on,If it's pure reading,Personally, I think K4 is more cost-effective。 The Kindle Touch (referred to as the K4 Touch Edition) has been available online since the beginning of December, and if you can wait, it is also a good choice!
