Yes, worth for travelling because of the weight and size compared to a normal book.

Need some steps to buy ebook from amazon. Still very easy for normal folks.

I got both the kindle keyboard and paper white. Paper white is better because of the built in light.

I can find most of the book I want from amazon store, you can search in the store to have a look first. If don't have then find in the internet lo.

Bought it direct from amazon with 3rd party forwarder, cheapest this way, waiting time is about 2 weeks.

If you don't want to go through the hassle of trying to buy ebooks from Amazon (because it's technically illegal), then I would recommend a Kobo. It's library may not be as big as Amazon's but if you're targeting bestsellers and popular books, Kobo will have it as well.

Amazon's Kindle (hardware and ebooks) are only legally sold in a few regions. That is why you don't see kindles sold in MPH. Even if you buy the Kindle online or something, you cannot simple go to Amazon.com and buy kindle books; Amazon will not allow it. There are ways around this by "tricking" Amazon into thinking you are from US. But it is actually illegal. Kindle device only allows you to purchase from Amazon.

Kobo is more open. You can buy Kobo from anywhere around the world and buy ebooks from any ebook store you choose. You can even load your own PDFs using USB, etc and read it on there.

Ooo like that Kobo not bad. TS, try Kobo Glo if within budget.
