Have had my A70IT for about a week now, after using an A7HTv1 for close to a year, and an A7HTv2 for several months. (Edit: Got the 8GB from the Archos store for $199 with Free shipping).
On the A70IT, I immediately put on a "Lexerd" brand screen protector (available from Amazon) and went straight for the latest firmware (2.4.65), followed promptly by running Appslib to load the latest Arctools, which got me the regular Android Market on the first try. As others have noted, the Archos 70IT doesn't show up in my Android market device list, but I can still install (free) apps on it, and while the Android Market website tracks my successful app installs and allows me to review installed apps, the Market app crashes when I go to rate/review anything using the tablet.
Also, the firmware-provided in-browser flash (10.1) works for me. I can cruise YouTube and see and hear videos.
This is not my first capacitive device (I have a small Korean-made music player), but it is my first capacitive display/tablet. As I've already posted elsewhere, I prefer resistive for browsing any busy website, because one can very precisely tap with a fingernail.
The A70IT is appreciably lighter than the A7HT (V1 and V2), but unfortunately, it is also "taller" than the A7HT when held in landscape orientation. It's not a lot when you measure it with a ruler, but the comfort improvement for one-handed landscape reading, while noticeable - thank goodness - is not as life-changing as I'd hoped it would be. One's hand is stretched further. My hands are pretty big, and I think most people would not find the A70IT comfortable using one hand to read in landscape. However, it's in portrait orientation that I was seduced - they've curved the back and it's really close to a dream reading device now when held in portrait.
The battery drain is pretty alarming. With WiFi OFF, and screen brightness kept at about 30%, the battery usage meter tells me that the screen is what's really sucking the power here, and I went from 99% charged to 60% charged in about an hour and half of reading (with a music app in the background). I was hoping that e-reading - my primary application - would mean better battery life than an average A70IT user would see (I mean, you just flip a page every minute or so, right?) but I seem to be experiencing the same quick drain that many others on the board deal with.
So in short, to make this my dream tablet, I'd sacrifice the camera and HDMI-out if that could bring the landscape "height" down slightly. I have no use for those things, but I understand that they're a big part of the tablet universe for most customers. In the matter of resistive vs. capacitive, that's a battle that's already been fought and I'm on the losing side, so I'll just have to get used to greasy fingerprints all over my screen cover.
I occasionally buy e-books from Barnes and Noble, so I appreciate that the nook.apk which someone posted in one of these ArchosFans forums a few months ago could get up and running on my new A70IT. I logged in and immediately saw all of my purchases, without benefit of the Android Market.
I only dove into tablets for bedtime reading - books and web and PDFs - with audio streaming a major consideration. With my A7HTs, I was able to borrow local library books with Overdrive Media Console, read PDFs with a great open-source viewer (apv) which worked on the A7HTv1, and used Aldiko for ePubs. The A70IT brings all that over as well as a nicer weight and feel, a newer OS, Flash support, more horsepower (although I keep power consumption downshifted), and also adds Nook app capability to its bag of tricks. It also keeps stereo speakers facing front, which I like. It'd be nice if the battery didn't drain so dramatically, but you can't have everything.
