The hardware still suffers from the odd stutters and lag with lots going on... i'm not talking as much about the GPU as about the CPU. My Samsung SGS III is noticeably faster in every respect and is only a notch down resolution-wise. This tablet will age quite quickly now imo, especially when compared to the releases due at the end of this year/early next year with the A15 cores. Am I happy I bought a tablet based on 2 year old tech that I will have been able to use as intended for only 6 months before the A15-based tablets arrive and make it look like a dinosaur? Not especially, and I will probably look to sell in a month or two to get the best price for it that I can so I can upgrade it when the new gen comes out.
Well it depends what you need extra cpu speeds for,to make the overall experience smooth everyone will agree with,but as people have said the 7.7 with ics is nice and smooth with minimal sluggishness.
I have just sold my nexus 7 (i was going to return it to google but didn't want to bother with sending it and then waiting who knows how long to get a refund),and i will say some of the things that annoyed me about the nexus 7 enough for me to sell it and thing to own a different tablet.
The first thing that bothered me was just the general build quality was not great and if you pressed with medium force on certain parts of the screen (this was for my model anyway) it would depress and squeeze,i mean i really liked the soft leather effect back of the nexus 7 and it feels great to hold,but i really didn't like how it would squeak and depress.
The second issue is that the nexus 7 gets too warm for my liking at certain parts of the back of the device (i presume where the tegra 3 chip is stored),ok it has 4 cores and offers a smooth experience (although i think that is mostly down to the software android 4.1 than actually having 4 cores, as next to no apps actually utilize 4 cores except benchmark apps,but i don't spend all day playing with them) it just becomes noticeable and annoying when holding it.
So those are really the two biggest problems i had with the nexus 7,for what i plan to use a tablet for,which is mainly ebook reading (and listening via text to speech which is a must for me and android's TTS apps blow away what any other tablet os can offer) and watching hd video and the like,this is the best tablet to do those do things.
I've really started to go off games altogether so that aspect is not a main point in my buying decision for a new tablet,but even saying that tegra 3's graphical improvements over non tegra devices is minimal at best.
Anyway all in all i defiantly see other people including myself who would look for a premium tablet that satisfy's there needs for what they exactly want from there tablet experience.
I have also looked at the ipad 3 seeing as it's in the same price range but when i argue portability and the quality of the 7.7 screen for HD video it beats the ipad 3 which doesn't even play hd video in full screen resolution and has the same viewing space as the 7.7 because it has about 1 inch black bars on both the top and bottom,where as the 7.7 is full screen native resolution.
