Nice form factor / size. Several extra features u can't easily get w/ comparable products.
I've had the trackball media center themed remotes and the balls are too loose that it errantly affects cursor movement.
Trackpad alleviates that.
L and R mouse buttons. Yes thanks.
Full Function Keys to F12 which helps get into BIOS and other system.
Embedded sensor housing? Nice touch.
Rechargable by standard USB port ? why thank you.
MULTI TOUCH trackpad? Really?? thanks.
Even a red laser pointer albeit not sure why, except maybe if you want to torment a pet cat? It works so I'll not complain of it.
For newest media centers and when you want to TYPE to search or browse this is a great complement to have for those wanting for Media Centers or just a handy portable keyboard to have around in a pinch for the price. 

Admittedly I'm not an avid reader. I can't recall the last book I read, but it would have had to be in the last 7 years, and likely a Michael Crichton novel or perhaps Matt Reilly's The Contest.
I'm a reader that when I get interested I can't put it down however. 
As a technology enthusiast I've long been intruiged by the Amazon Kindle. I always thought I wonder if more convenient would I, a rabid tv/movie fan, actually READ?
Those whom know me, know I use my 'stuff' extensively / exhaustively. Would this be something I procured then subseqently never used? I would hope not. However being hardened through several versions and priced at a deal I couldn't pass up, I bit the bullet and picked one up.  Its TERRIFIC. 
As a previous owner of an original Apple iPad and a HP firesale TouchPad.  I refuse to read on a backlit screen as its clearly irritating to my eyes.
The contrast on these is terrific. I literraly sat on my portable hammock this weekend and read in broad daylight. The latest Kindle firmware update was painless and effortless to load and even improved the contrast/font a bit.  With Calibre a freeware (portable app available) you can even load RSS feeds to convert and auto send to Kindle and convert other files for viewing.
An ancillary use case I see for this is loading all your manuals, for easy access. Your TV manual, computer manuals,....etc all preloaded here for easy acess when you need and handy when actually using / fixing something.
The weight (balance) are great, in the hand to read and it fits a rear jeans pocket easily. A great impulse buy. Read a 1 1/2 books on a single charge with a SLOW reader. Not since the Nintendo DS have I been so pleased with battery life. Totally reminds me of being inspired by PADDs by Star Trek.
I traveled abroad about 9 months ago and am kicking myself I didn't have this for the 14+ and 6+ hour flights!

Recently I've been late to the game and gotten hooked on the Food Network and also trying to learn how to cook some more.
Got this new chefs knife and its terrific. Affordably priced and well reviewed with lifetime warranty. Victorinox 40520 Fibrox 8-Inch Chef's Knife
