[Nexus 10 General] HoushaSen:
My input is biased as I have not owned Nexus 10, and may not ever. Still debating.

But I have done extensive research about all the major tablet out there including Nexus 10, various windows 8 tablets, and owned Infinity myself for about 3 months or so. I sold it in anticipation of Nexus 10.

So here are some of things I can tell (nexus 10 part is just a speculation, and definitely guys own the device can tell you better)

Screen - Nexus 10

Infinity's screen was phenomenal when I jumped from iPad 2. Then I got Note 10.1, and just could not tolerate the lower resolution anymore so had to go back to Infinity. I am not sure if the Infinity to Nexus 10 gives the same degree of jump, but it is possible if you purely look at difference in number of pixel densities. Though one thing I can say is if you never used higher resolution screen, it's hard to know what you are missing. Because I saw new Ipad several times, but until owned Infinity myself and used for couples day I really did not appreciate the difference.

Battery Life - Infinity.

Charge time is faster, extra docking battery, and perhaps tablet itself already has better battery than the Nexus 10 according to paper.

Extra storage - Infinity

MicroSD. I am sure you can connect couple cables via microUSB and use them on Nexus 10 as well, but certainly not as convenient and visually not as good.

Build Quality - Likely Nexus 10

I have never exchanged any of my electronics before in my life. With infinity, I had to do it twice and seems like quite few complaints on the forum here. So when you get a good unit, it's great but there is chance you might have to go through couple exchange. As far as light bleed, some person posted on this forum that Nexus 10 has light bleed. That was actually worth if not the same to the worst light bleed I had on my 3 infinity tablet i.e. both have light bleed.

Dock station - Its really nice to have docking keyboard on infinity. People are hoping Pogo connector on Nexus 10 to support this, and personally I am dreaming the same. However, to be honest, I am not even certain that connector support such type of input.

Application Performance - Likely Nexus 10

Overall performance is likely stronger on Nexus 10, but so far reviews I have read across multiple sites sounds like not a complete ground breaking performance. Nexus 10 certainly has better GPU than Infinity, but supports way more pixels. CPU wise, perhaps it may be due to the fact the some benchmarks are not yet optimized for A15 architecture, but if you look at some benchmark like Antutu Infinity is superior. (Mainly because quad vs. dual core difference I believe). The other test is Sunspider, which is browser test. After the latest firmware update, Infinity's stock browser gives 900's score. Clearly above the Nexus 10, but nexus 10's score also likely to go up. However, there tests are generally just number and I don't think not true reflection of real experience by any mean.

As far as slow internal storage, it is true that Infinity uses inferior internal storage; however, whether you really notice this as major issue or not is depends on how you use your tablet. Initially, people complained this as a cause of slow browser page loading, near complete stall of system while application downloading. Also, relatively frequent application not responding errors. These have been alleviated by update; however, not eradicated. So wonder how Nexus 10 solved this.

Wifi Performance - Nexus 10

MiMo should give quite extra wifi performance.

Future proof - ?

Nexus 10 will definitely get quicker updates on OS. But ASUS is also very fast in fact it has been one of the fastest to get OS update among non nexus device. Though actual overall internal hardware is somewhat inferior to that of Nexus 10, Infinity drives less resolution so it may be relatively sufficient for what it has. If so, as developer supports more higher resolution applications on Android platform (to support Nexus 10), Infinity will also benefit at the same time. So my guess is unless Asus gives up, relative future proof are probably similar between the two.

Conclusion

In current stage of tablet market, I just don't see any tablet that is perfect or completely superior to other competitive device including Nexus 10, Infinity, and Galaxy Note 10.1. Personally, I want a tablet with high resolution screen, luxury of Infinity's dock, microSD, and Galaxy Note 10.1's stylus. WIth zero crash, 10 hours battery, less than 600g... Closest I see for potential right now (myself) is Windows surface Pro but even it lacks battery life, and weight factor. Maybe Samsung's next tablet (Galaxy Note 10.1 with high resolution screen)... I think you just need to list what is important for you and decide.
