I've been a Kindle owner since the very old and chunky Kindle 2 device. Here's my personal pros and cons on the new Kindle Touch:
PROS ON THE KINDLE TOUCH:
1) Smaller and lighter than my previous Kindle Keyboard model. Dispensing with the physical keyboard and using an on-screen keyboard has saved a lot of space. This makes it nice and light to hold and also it's now small enough to fit into most of my handbags too.
2) The touch aspect is very responsive which is both good and bad. It's ever so easy to turn pages with a very light press on the right side for moving on a page or left for moving back. You can also swipe to turn pages too which again is very easy. I love the fact that Amazon have added up and down swiping while reading which means you can move to the next or previous chapter very quickly - if chapter markers have been added by the publishers in the book.
3) Using a touch screen is probably more intuitive for most people who are used to tablets and touch screen gadgets. It's great to be able to simply touch a word and you get your dictionary definition rather than having to navigate down to a word using buttons and then select it which is tedious.
4) I was very concerned about fingerprints over the reading screen but I've been pleasantly suprised with that. You do get fingerprints but they are admittedly very difficult to see on the matt finished screen unless you look closely. So hopefully that shouldn't put you off if fingerprints are a worry.
5) The text is clear and easy to read with lots of options of changing the size of the text and a few options on the font - just the same as with the Kindle Keyboard model. I compared both screens on my old and new device and noticed no difference with clarity of text between the two models.
6) Great new X-Ray feature (only works with some books where the publisher has provided it) which means you can see more info about characters, events and places with your book. This has been brilliant with reading the Harry Potter books where sometimes I want more detail. No having to go online to look it up - the extra info is there for you.
7) Some operations are made a lot easier with the Touch model like selecting words to get a dictionary definition, highlighting your favourite passages and quotes, adding a bookmark by just pressing the top right corner etc.
CONS ON THE KINDLE TOUCH:
1) I can't type as quickly on a touch screen keyboard as I can on the physical one on my Kindle Keyboard model. This may not be an issue for most people but I use my Kindle as a research tool as well as to read books so sometimes I can make extensive notes. This will be a pain for me with the touch model - plus sometimes my fingers press the wrong key on the Touch model because they're not very big.
2) The touch screen is very responsive which has its good points as I mentioned in the pros. But it also causes some issues too because if I don't press the power button when I'm done reading to activate the screensaver right away then any accidental movement on top of the screen causes something to happen which has ended up with me losing my place while reading a few times. Also my clumsy fingers have pressed on screen items by mistake on a number of occasions causing me confusion as to where I was.
3) I definitely seem to get more screen ghosting with this model than with my Kindle Keyboard so I'm a little disappointed in that. First thing you might want to do when you get your Touch is to go to settings and make sure you get the device to refresh the e-ink on every page turn. If you don't then I kid you not, you will see parts of the previous screen 'ink' on the current page that you're reading and this is known as screen ghosting. It's very annoying. Even having the page refresh on every turn, I still get a little of this ghosting so that's a slight con for me.
4) My BIGGEST CON with this new Kindle is the lack of physical page turn buttons. Yes, I know it's a Touch model but personally I'd prefer the option of being able to use page turn buttons while reading OR to use the screen to navigate. Problem with using the screen is that your thumb (which you'll use to move forward and back whether tapping or swiping) ends up obstructing some of what you're reading. If you're a fast reader and turning pages quickly, this can be pretty annoying. I love the physical page turn buttons on my Kindle Keyboard and I just wish that Amazon had provided them as well with this model. Personally I don't want to have to touch the screen to do every single thing.
So while I think this new model is great and has many advantages over the Kindle Keyboard, I'm not giving it a full-out 5 star rating because the device isn't quite perfect for me. I don't see any improvement with the sharpness or clarity of text over the previous model, I do get a little of the annoying screen ghosting and I just wish Amazon had provided those physical page turn buttons as well so you're not forced into having to read by touching (and covering) the screen.
And that's my very honest take on it. Great model but just missed the mark of being the perfect Kindle model for me.
