+My Kindle 4 has been used for almost 4 years, I read about 200+ books and 500+ articles
+on it. After years of using, I have some thoughts about this e-reader.
+
+
+## What e-reader features I want actually?
+
+I want my e-reader to do these things well:
+
+1. Read papers and make annotations easily.
+1. Search fast, scroll fast.
+1. Larger screen (which makes a huge difference on reading paper).
+
+
+## What my Kindle 4 provided?
+
+1. Cozy reading experiences.
+
+Kindle provide a paper like reading experience, though I have not used Kindle
+paper white yet (which featured with higher ppi). I really enjoy reading novel
+on it.
+
+But due to the small screen size, I cannot find any good ways to read PDF (mostly scanned books or papers)
+on it.
+
+2. Perfect battery life.
+
+Kindle 4 was featured with 1 month battery life and it is not a lie.
+I am (maybe was :D) a bookworm as I can read on Kindle for about 1 to 2 hours
+every day, and believe it or not, Kindle 4 can continue works for 10 days before
+next charge. After 4 years using, it still gives me fantastic battery life usage.
+
+3. Kindle is cheap.
+
+If you compares 500RMB with 200+ books.
+
+4. Kindle help you foucus on reading.
+
+Slow refresh rate, no multitasking, only thing you can do is reading.
+
+
+## Conculsion
+
+So comparing the features I want and Kindle can provide, I choose to move on to
+a new reading device. I may give iPad a shot later.
+
+And is Kindle recommended? My answer is up to your usage. If you just want to read
+novels, news or articles, Kindle is a perfect choice. But if you looking for
+good experience on reading technical books (like code snippet) or papers,
+Kindle may not be the perfect gadget for this.
