there will be no tablet/phone without any issue
its all depend on ur tolerance toward those thing

to some ppl the screen color is consider issue. to some ppl they like the color

Bought my Nexus 7 32gb 3G version 2 weeks ago. No known faulty parts. Works like a charm. If you wanna play safe, buy from SenQ as they have 1+1 year warranty.

Screen Lift / Separation 
Headphone Socket Not Working 
Wi-Fi Dropping 
Battery / Power Drain 
Defective OEM Charger 
Battery Will Not Charge 
Dead Pixels 
Light Bleed 
USB Connector Broken Out Of The Box 
Touchscreen Non Functioning 
Crackling Speaker 
Screen Tearing

Amongst all these issues listed, the one i've seen here are screen lift, power drain, crackling speaker. That's it. Probably i missed out on the earlier Nexus 7 thread and there are those who faced with those problems. But it just prove to show new users doesn't face with those issues.

Nope, I bought from SenQ, with free casing.  The faulty parts are getting less and less, back on those days when the batch code c70 and c80 that time got many faulty parts. But now since V4 thread, I don't see much people complaining about getting faulty units.

Just realised this Sony tablet specs quite solid. improved design looks nicer aswell. I would say if you prefer a bigger screen should go for that one, on the pretext that price is not an issue.

Confused with the previous model. But this new one is alot better than the first one. Specs wise and design. Made up your mind? The sony tablet is a more complete tablet. But Nexus 7, if you can live with the shortcomings, should serve you just fine. 

No back camera,no micro SD,some app not compatible with latest update,that's all I guess

I will use phone instead,straight away can get in my nexus 7 through sync,no need use tablet so big

For me rear camera is not that useful, I can use my phone to take photo, scan QR code or whatever a rear camera can do.

But expandable memory really is something useful, I would say the device will be complete if it has expandable memory. But consider the price, I would say this is a trade off.
