This review focuses on Kindle DX with many screenshots. Obviously it has been reviewed on several sites and well researched into. I will share my 2 ¢. I considered Kindle DX over an iPad style tablet mainly for its sole job of rendering texts clearly with EInk technology. I wanted something very similar to a paper, and ability to adjust fonts and make reading a interesting experience. With that requirement, Kindle DX is excellent and meets all requirements. Ability to read pdf is also excellent in Kindle DX. The software needs to be improved a lot and I am sure Amazon is working on it. I am fully aware this is still in its infancy and it is like PCs in mid 1980s. In another 10 years I am sure, the technology will be far superior. We will look at several screenshots. One main issue is it is still not available widely in stores. So one has to buy and feel for it. The reviews only gives an idea, there is nothing like using it.
At the time of this writing, Google ebooks also made entry and this is definitely a crowded market. Google does not have a dedicated ereader, but may hope for its Chrome OS based netbooks to deliver the reading functionality. But it is not EInk still. The competition is always good!
Overall Summary of Kindle DX (current generation Dec 2010).
- Definitely book reading experience is great. Screen size and display is great, size excellent. Resolution, font size change are all excellent. For its primary purpose it is great. As Jeff Bezos mentioned, Kindle audience loves to read and likes Hemmingway, and does not play Angry Birds most of the time as they do on other devices. (am paraphrasing it here).
- I preferred a DX as I want to read user guides/manuals/Sanskrit pdfs and this is far superior than on smaller Kindles.
- Book buying experience is great. Sample chapter is excellent.
- Text to Speech is excellent. In reading of a whole chapter, it was excellent. Some improvements. Better treatment of punctuation. Better context sensitivity. “IT WAS” was pronounced I. T. Makes sense in a different place. Speaker is great.
- Weight is about right, less weight always welcome.
- Word Games are added bonus. Helps to keep kids occupied with word games rather than some junk games.
- Reading PDF docs is great, sensed all of my pdfs including Sanskrit, Tamil etc. rotation mode works great.
- Black and white is great for me. I don’t want to strain my eyes on a LCD screen. People who say this does not stack to iPad should get a iPad. It is there for a reason. This is like comparing apples to oranges.
- Blogs/magazines are ok, nice add on, but I rather read them on computers. Why are they paid? I would rather wish Amazon team up with advertisers and develop a good Ad model and make blogs and magazines free. All blogs are free on internet anyway and being a very immersive experience in Kindle, Ads will have a very strong impact and will help Amazon financially. Right now, I doubt there are many subscribers to blogs.
- Would like buttons on both sides. I am afraid buttons may fail anytime. A sturdier mechanism will be good.
- Keypad buttons are right, wish the letters are brighter or more legible. A permanent caps lock key will be great. I wish the nav key is more like in Kindle3, I think the button which moves left right up down may break after long use
- Frequent Software update will be good. I do get memory errors after some use of experimental features.
- Experimental browser needs lot of improvement, but it is great. I definitely want Amazon to continue work on it. Pages don't refresh, sometimes I have to go back and come in again on browser windows.
- No Wifi. This has been mentioned million times. I wonder why Amazon left it?
- Folders is a must. I have 400 pdf documents, making collections and managing them is becoming a nightmare. If I have everything sorted as folders in PC and I drag it, it should appear as a folder view. Collections though ok, is not easy When I want to add some pdfs to a collection it shows all 400 pdfs again. I don't think one pdf need to go into multiple collections. I don’t like sync programs, but some sort of usability improvements is definitely warranted.
- Auto wireless off during inactivity will be good to increase battery life .
- More storage space! 8 or 16 GB. With ability to store music also, it is highly desired.
- I like to have custom wallpapers. Let me create a screen_saver directory and put few family photos. Use that instead of authors.
- Misc: Runs Linux 2.6, busybox. Is there a GPS? I read on forums this has built in GPS?!
- Overall nice device, though there are several improvements possible. I will give a 4/5.
