I am *so* glad I traded a (refurbished) 8.9" in for a (new) 7"!! The refurbished unit was like new btw. But having grown accustomed to my previous 7" 1st gen Fire, this is just right. There are also minute differences on the keyboard, etc. between the sizes that I was already used to. I think the 8.9 is too big and heavy; and this one is just right :) Love Fire in general, and enjoying all the new functions, especially the audiobook/ebook synchronization, as well as the new standard text-to-speech voice which is certainly improved on the original. I am also for the first time typing on the bluetooth keyboard which paired perfectly once I figured it out and types amazingly comfortably (by Amazon), plus the original (leather) Amazon case (in blue); the difference in price between the sizes allowed me those extras (and a charger). Works great. Also there is a phone app so you can make and receive calls. 5-Star performance! :)Update:  I returned this unit for a refurbished non-HD (gen. 2) Fire. I just don't think the HD adds anything (the screen of my original Fire is perfectly responsive and visually; it doesn't have the slight pauses or glitches of the HD. I reasoned the 10-point touch screen & HD-quality "video card" (or whatever a Fire has) takes more RAM and software to operate, hence possibly accounting for the difference from my *perfect* 1st gen. unit. I watch Netflix and HD-quality YouTube videos on my 1st gen. and honestly don't see a difference. I also know the refurbished units are just as fine and functional as new ones. I got two more cases with the deal, one being a duplicate of my favorite which is hard "fabric" that completely zips around unit and has no "straps" (Marware beige)Marware jurni Kindle Fire Case Cover, Beige (does not fit Kindle Fire HD)Most of the new features like text ebook/ audiobook synchronization (immersion reading) are included in the new (2nd gen.) software and I'm hoping the new text-to-speech voice software is as well. They are not HD-dependent. Of course I am sacrificing Bluetooth functionality (keyboard, separate speakers), HDMI-out for a larger screen, and one App that allows you to use the device as a phone; probably the microphone is missing too, and of course the camera is (mine was too dark and grainy anyways, not nearly as good as a built-in laptop cam for example). So, no Skype on the non-HD if those features matter to you (the phone App was neat).My main beef was the screen, again in the HD 7" Fire was yellow, with less contrast (for text ebooks) than my 1st gen. which I far preferred. Mostly I use my Fire for reading ebooks, and that was what was important to me. I keep my half-way brightness setting, and it's always sufficient. Secondly I browse websites and videos, and my 1st gen. is nimble & quick and perfectly capable. So I'm hoping the 2nd gen. I have now ordered will have the hardware designs I prefer with *some* of the new features (software). I can only hope for the quicker, brighter screen; I know the interface has been updated to the new standard which I found equally useful to the original. It is shipping now... :) As a small last insertion, the Kindle (ebook reading software) function, in the updated version, covers the text of your ebook with the menu enabled at the top, more like the Kindle White. The old Fire doesnt do this; it does, however, do it on the bottom. This will be the same between the HD and 2nd gen., so just a minor irritation. Btw, I received the sale price of $169 here so the difference in price between the HD and non-HD unit was a non-issue.I removed one star for the more yellow, darker screen with less ebook text contrast. 

Question: How big is the unit?
