nvidia tegra 3 as well as 4 are fail due to higher power consumption and less performance per watt.
tegra 4 does not even have single tier one parter like htc or likes.
already reuters is reporting qualcomm snapdragon based second gen nexus that too at lower price points.
what does that tell you??
you all nexus lovers wont see the point and keep paying for stock clearance stuff at full market price.
in usa,this stuff is already availble for discounts and here you keep paying full price.
anyways if you dont value your own hard earned money,keep buying old junk.
I never.upgrade as per.manufacturer cycles.
my 6 yrs.old vaio still runs absolute fine with new battery and ssd.never felt need to upgrade to core i.
its screen color are still excellent and I find panel quality far better than current gen systems like.thinkpad e430 which I got for my sister.
