I think what you would want to hear is from someone that has owned the product for 6-mos to a year.  I've only had mine for a few weeks, have used that USB charging port daily and so far, nothing has broken.  But, I'm careful with it, taking a few extra seconds to make sure that I'm not jamming it in or putting any undue stress on it. 
 
I can say that I don't like the way it feels when I plug it in.  A lot of that has to do with a more loose feel than what I'm used to seeing with other portable devices.  It is just not very snug (laterally) after you plug-in the Micro-B connection on mine.  It will rock easily if you move it laterally and has a bit too much play for my liking.  However, I can't (yet) say that there is a design issue since it has not broken.  I looked over many reviews of this product and while a great product, some people have reported issues/failures with that USB port.  Not knowing how they treat their tablet, some of the problems could have been self-induced.
 
Time will tell for me and I'm not really that worried if it does fail since electronics is my background.  Assuming I can get to that connector, I can dismantle the tablet and repair/replace that USB port receptacle in the future if it does break.

Hey there johnerz!  Another one of our Bros (Yodap) from Folding/Crunching-land recently got a EVGA Tegra Note 7 too.

I've had mine since launch (I pre-ordered mine), and I've had no problems with the USB port at all until literally yesterday, but that's entirely because it slipped out of my hands, and the USB plug hit right on the edge of a table while plugged in, so it jammed it pretty good and is kinda hard to put in and out now, but it still works, even after a direct impact with a cable plugged in. It's always felt a bit wonky, hence everyone's concerns, but if you aren't rough on your devices, this thing should last you just fine. If you're pretty careless, then you might want something more rugged.

After all my carefulness with the USB connector, a couple weeks ago my Tegra accidentally slid right off my desk and dropped a few feet to a hardwood floor.  I think it was "trying to make a statement", but I couldn't hear it because I was in the middle of a full fledged cursing maneuver watching it fall.  I figured, well to heck with the USB connector, here's gonna be a cracked screen for sure because it landed on it's edge.   But to my relief, nothing was damaged and it was still running fine.  I have that optional Tegra Note magnetic cover on mine and I think it may have taken the brunt of the landing.

Had mine two months and in the last few weeks the problem I noticed is that the mUSB connection itself isn't snug, a slight tilt in the plug causes the power connections to be lost and the battery doesn't charge properly.  The tablet is in the middle of the table, but if I bump the table at night, the connection looses contact while still plugged in, then I'll wake up the next day and see it never charged.  I thought of opening it up and MacGyver'ing my own battery, but is this something that warrants an RMA?

If it's in warranty, it is definitely covered and you should send it in.

...if you are doing a similar rocking motion and losing connectivity, then your TN7 USB receptacle sounds flaky to me.

That is exactly the problem right now, it annoys m that it won't charge properly.  Would you think an RMA is what I should be doing, since the tablet is working fine?
 

I got mine back when it just came out and it still works just fine. I am not sure if most people realize you need to insert the plug at an angle, instead of push it straight in like most other devices. Honestly I think this is by design since it seems to lock in better than many of my other rechargeable items. 

an update my antics as I've buying busted ones off ebay to tinker with.
 
wireless chargers do work and with minimal soldering, I was concerned about the machine not registering the charge but the chargers are smart enough to switch off when the battery is full.
 
works a treat with the slide cover but you have to remove it from the fintie case so at least with the QI chargers it is feasible to take apart a charger plate and slide it between the layers of a case and fix it so you plug into the case and it charges the tablet allowing you to carry on using it.
 
only have QI kit to try it with but powermat stuff can be picked up dirt cheap and the receiver cases dismantled to get the important bit. powermats have locating magnets which makes lining up easier. you can get two blackberry cases for around £3.50 or an iphone three set for £4 - bargain.
 
other wireless chargers are available to dismantle :)
 
I have asked various places about socket repair and one even said he would just replace the plastic inner which I didn't feel would solve the problem of having the wrong shaped socked in the first place.

Someone had mentioned this somewhere a while back, but it's actually because they used the wrong connector. The tablet has a Micro-USB A connection, but almost everything else, including most charging cables (and the one included with this tablet), has a Micro-USB B connection. The Micro B cables will fit into a Micro A connection, but it's not a snug fit as the A connection is fully rectangular without the little indentations found on the B connection. Check out http://www.cablestogo.com/learning/connector-guides/usb and take a look for yourself if you're not quite sure what I mean.

I think someone posted that the Micro-AB receptacle  was used so that the TN7 would be compatible with the USB plugs used worldwide (which can be Micro-A or Micro-B).  So, there is a "looser feel" for those of us in the US that are used to connecting Micro-B plugs to Micro-B receptacles.  For me, it is just a loose feeling that I don't prefer, but it has not failed (yet).  I have never damaged a USB Micro-B receptacle by plugging-in a Micro-B plug on any of the many devices I've owned.  This tablet's USB connection is the first device where that loose feel has me being more cautious when plugging-in the charger.
 
My greatest victory in gaining better usability of the TN7 has been Rchrdcrg's suggestion of not closing the magnetic slide cover for the TN7.  That has greatly improved usability (and removed a couple of nagging issues) for my TN7.

mine did that and broke the cover - they don't seem that well put to together especially for the money - I had to do some surgery with hot glue, craft knife and a paper clip to get it functional again now I think the other side is going so switched to a fintie slate 7 extreme case which also take my wireless modding. not as flash but I dont need a seperate cover to the cover as it was popping apart in my bag. nice design but a bit more thought required methinks.
 
just posted wireless solution for those with working sockets who would like to keep it that way and not open their cases.
