Note: I am using the 7/24 PDN firmware (hacked, of course) and the OF on the Gentouch, as of this writing.Where the PDN wins:- ACV Comic Viewer. Between the wider screen and the fact that is actually WORKS on the PDN, it wins hands down.- Skyfire. Has the same screen issues on the Gentouch as ACV - that means there could be other apps with this problem, and that's not looking good for the Gentouch.- Accelerometer. The Gentouch can go into portrait mode depending on the app, but that causes other issues once you leave the app as it gets "stuck" in that mode. Very annoying.- Battery life. This is assuming both are hacked at similar Mhz levels. I am not 100% sure of this yet, but limited testing seems to indicate that the PDN wins here. I'm going to do a better video playback test once both my devices are fully charged up.EDIT: More testing seems to confirm that. Fully charged, ran the same 30 minute MP4 video on both. Once done, checked the battery -- 85% charged on the PDN, 61% charged on the Gentouch. Let them sit for 15 more minutes idle -- the PDN is still 85% charged, and the Gentouch is now down to 58%. Both have WiFi enabled, btw.- Recharge completed green light LED. Never really realized how much I liked that little feature until I found it lacking on the Gentouch.- Typing accuracy. This is an early lead and could change, since it's so subjective. Maybe it's the larger screen or perhaps I've become "used" to the PDN, but I find typing on it more comfortable than the Gentouch.- Ability to change the brightness. So far, I have yet to find a way to do that on the Gentouch. When running apps like Aldiko on the Gentouch, it's either 100% brightess or 0%. There is no in-between.- Font quality. Not just on Aldiko, but also noticeable on the homepage. The Gentouch is a bit "jaggier". In particular, Aldiko night mode (which I use a lot) looks better on the PDN than on the Gentouch, imo.- Heat. The Gentouch feels more like a laptop, as it generates some heat (I assume from the battery). The PDN does not have this issue.- Ability to wipe the device, if needed. No fix for that with the Gentouch, yet.- No need for a 3.5mm headphone converter, to use standard headphones. Granted, it's probably a $2 item to fix, but still an annoyance.Where the Gentouch wins:- Video playback. MP4's play more smooth (especially 4:3 playback, where the PDN gets choppy). I haven't been able to get AVI's or MKV's to work yet, but just the MP4 playback improvement makes it the clear winnner.- Overall UI performance, once rooted and altered with SetCPU. And once you kill the animated wallpaper, too - bad design move on Augen's part, there.- WiFI. Sleep/power-on speed and reliability is noticably better than the PDN.- Notification Bar works from the get-go, no tricks needed to enable it.- No crashing on rotate versus the PDN. But not a 100% win since there is no rotate at all. - Web browsing. Perhaps it's the smaller screen or the WiFi, but it seems a better performer to me, via limited testing. Also loads faster, assuming I test with the default browser on both.- You get a nice case.Neutral, so far:- Buttons. The Gentouch has more, but I personally like the side placement of the PDN better. So take your pick, here. - Audio SQ. They are not the same, but I haven't decided if one is better than the other, yet.- Size and weight. The PDN is larger and is probably heavier, but the Gentouch feels cheaper. So again, take your pick.- Having to mount to get USB PC connection working (Gentouch) versus automount (PDN). I don't really have a preference.- Overall screen quality. I think that Aldiko looks better on the PDN, but I think videos might look better on the Gentouch. I think it depends on the app used so I haven't really decided yet.- SD (PDN) or MicroSD (Gentouch). I personally prefer SD because I already have a 16GB that I can use, but it's up to you what's preferable for yourself.- The speakers. They are both crapola, to be honest. Maybe the PDN wins out by a hair, but I'm not calling that one yet.
