[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] BarryH_GEG:
There were some early assembly issues (S Pen loose in silo, speaker grills uneven or loose, BT connectivity issues) that seem to have abated because after the wave of early builds they haven't been mentioned lately. If you're a lag-freak the N10.1-14 does suffer from the occasional transition stutter or milliseconds of lag opening and closing apps. I'd peg it as lag free 95% of the time. We're getting Magazine UX/4.4 soon and the Tab/Pro's shown on video from their CES launch looked much smoother than the N10.1-14. Do you have better than 20/20 vision? A couple of people who do (or apparently do) have noticed some display anomalies when looking at certain content; most likely because of the N10.1-14's RGBW PenTile display. I can't replicate it but have only mere mortal vision.

The top reasons to get the N10.1-14 are:

Display. I think it's gorgeous no matter what anyone else says and I compare it against my N3 everyday.

Form factor. Amazingly light, slim, and small for a 10" tablet.

Doing stuff. S Pen, S Note, Multi View, Action Memo, Scrap Book and the like are huge productivity benefits and once you start using them they are hard to live without. I'm on my second round of "Notes" with the N3 and N10.1-14 replacing my N2 and N10.1-12.

The top reasons not to buy it:

You're a pure consumption user. All of the extra features of the N10.1-14 use a lot of resources and if you're not going to use them will just be annoying. You pay a lot of money for the N10.1-14 because of those features (and premium h/w that's needed to power them) and to not use them will leave you frustrated.

You're a lag-freak. As it stands there's some stuttering, hesitation, and lag about 5% of the time. It's most prominent when there's a bunch of background processing going on. Some of the proprietary apps can throw up a spinning wheel while they're processing. For example you can move content between two apps open in Multi View. It's not always instant. You can also use Air Command to copy full screens of content from various sources to be saved in your Scrap Book. It too isn't instant.

You have super human vision or live-and-die by a "perfect" display. Some people here (a half dozen?) are really freaking out about some anomalies they've detected in the display. Interestingly, other than a single reviewer who actually has 20/15 vision mentioning he noticed "something different" about the display no one outside XDA has mentioned what some folks here have found/described. The difference between a RGB display and the N10.1-14's PenTile display is that because of an indirect sub-pixel arrangement, in certain situations like specific saturated colors on specific backgrounds, there can be detectable imperfections on certain content.

Since you're leaving the G Pad over its display do yourself (and the forum ;) ) a favor and make sure your display expectations are met

before

you buy a N10.1-14.

Assuming you're not buying an LTE version, the Wi-Fi and 3G versions take a looong time to charge; as long as seven hours to get to 100%.

Happy shopping. ;)
