[Galaxy Note 10.1 General] HoushaSen:
Perhaps I may be a minority here (especially this is note forum) but assuming there are still people out there considering between the two, I ended up choosing infinity after long trail with 4 weeks of Infinity (2 units), 3 weeks of Galaxy Note 10.1, then now back to Infinity (3rd unit) and decided to keep infinity and returned Note.

In short, I agree with others that Note is pretty much better in every aspect except screen. This is true statement. However, for my use screen resolution turned out to be such an important factor. I noticed the difference every seconds I stare at the tablet as my primary use is reading, browsing, and watching lecture videos.

So for this what did I gave up? Browsing speed, relative stability, S-pen, and extended battery life. However, compared to my initial two units, third unit seem to act much better and these sacrifice are minimal (in my opinion) and concluded not worth sacrificing FHD. Here are sacrifices:

Browsing speed:

In note, stock browser works perfect. Speedy and stable. In infinity, this is not the case. Boat browser is fast, and stable for me. But to truly gain the speed boost (especially for stock browser), you need to Root & install Browser2Ram. Even after this tweak or using alternative browser, things never got as fast as Note. So what's the difference we are talking here? Heavy Flash site I got almost twice the loading time on Infinity with like 20 seconds to load compared to 10 seconds on Galaxy Note. Fortunately, I only load these pages couple times a day so losing 20 extra seconds each day is acceptable for me.

Relative Stability:

At this point I am not sure if my original two units were defective internally. But my third unit, I have got only handful of ANR at beginning and after factory reset, I haven't noticed any. This may perhaps be related to bloatware turning off as I did not do with my prior two units. But this time I did this from the day 1.

Random close on browser still occur on infinity. It happens only on specific application mainly browser with heavy flash site for my use. This is like once every two or three days. For Note, once a week. But fortunately, this is my leisure use time so I can tolerate this.

Battery Life:

Infinity gives only 5-6 hours of battery on tablet alone; whereas, Note with the identical usage I get 10+ hours. Though as I have decided to keep my infinity, I finally got keyboard dock with extended battery. And I just realized not only it provides keyboard functionality and make it like laptop, but I can simply use it as portable charger. I can charge my tablet while I drive, or at work with keyboard docked as I watch video.

Then I come back home. The tablet has good battery remaining. So simply recharge dock, and continue using tablet in bed for ebook reading. Essentially, I never have time that I cannot use tablet because it is getting charged.

Though this is probably not issue for most people with Note as its extended battery life and most people can charge before going to bed. But any event, I found battery life is no longer much downside for me with keyboard dock.

S-pen:

Anyone says stylus can provide equal experience as S-pen, that is total lie. Inductive screen and captive screen are simply different technology. I was amazed how small I could write on the S note and still accurately recognize. If this is function I needed, I would definitely kept Note but my writing is horrible and I can type faster than write so this function is just not part of my daily use.

So yes. I did gave up quite few things by choosing infinity but it all depends on the individual use. One thing I can tell is one way or other, don't buy extreme statement one makes. Such as infinity froze, crash every time etc. I don't think anyone is lying here, but QC issue on infinity have good number of bad units floating around there. This is probably the reason why XDA forum section has some complaints whereas, infinity continues to get the best review across the board (internationally). There are some tweaks you can do to make Infinity better but you can never make HD screen into FHD. But again, tweaks take time and effort, also even after such tweaks not quite as good as Note. But its all relative. So best thing is just list what's your main usage and figure out what is more important to you.

In any event, Galaxy Note 10.1 is phenomenal device and I don't think anyone would regret getting it.
