Question: Can anyone use the USB cable to add, change, delete, files on an optional mounted micro SD card???  I have to remove card and use slot on PC case.
Document: This is a great, powerful tablet. Got two of these after a pair of cheapo's crashed after a few days use. The main use was to be gaming and other entertainment for the kids. But these offer so much more. Super fast, great display, responsive screen, gps, card slot, the pros go on and on. The only con is the micro USB port. The location is not good for me, on left when in portrait or bottom in landscape view.
I felt like the charger on my previous Acer was a major design flaw.The great thing about this tablet is besides having a micro as card slot, it also has a usb port so you can transfer files easily. I have a 32 GB thumb drive loaded with movies that I can just plug in If I want to watch movies.Lots to love with this tablet!! !
This device has 16GBs of storage like the Kindle Fire HD. This devices runs Android 4.1 (Jelly Bean) by default.Samsung Galaxy Tab 2 7.0 - $199Pros - Performance Speed, GPS, Micro SD Card Slot, Google PlayCons - Screen Resolution 1024 x 600, No HDMI Out (they make a hdmi out adapter for the other galaxy tab/note models but not for the 7").Notes:  Only 8GBs of internal storage like the Acer Iconia A110.
Overall this is a nice Android 7-inch tablet for the money. However, I ran into two snags I wasn't expecting. First, it appears that the USB port is not OTG USB compliant so even with a micro OTB adapter it will not work with a mouse, computer keyboard, USB drive, etc. It only seems to sync with a PC via USB. I purchased this to able to work with an external MIDI music keyboard and it does not work for this reason. Very disappointing.
I used A500 for a few years and was satisfied, I decided to decrease size of my tablet so it I bought A110 and it is really fine for me.It works enough long, enough fast and it has all features I need.If compare to Nexus 7 (I have it too) it has lower weight, let me insert SD card, supports USB-OTG (not tested yet)
Only 8GB internal storage without adding a micro SD card. I am able to stream amazon flash based videos by downloading a different browser than the stock chrome.
Most stores did not even have any in stock, as I was told, they only received 2 per store for sale anyway, and not all stores received any at all for sale. Nor does BestBuy carry the Nexus, so I had to purchase the Acer as well as the Nexus for a side by side comparison.I had purchased the Acer first, as this is the tablet I wanted because of the HDMI and SD card slot.
That negates the SD card slot on the Acer. Besides, the Acer only accepts up to a 32gb sd card. It has 8gb internally, so you do get 8gb more even if you don't find a way to enable a flash drive on the Nexus. I do like the idea of being able to have multiple sd cards to swap in and out with movies, music,etc. without having to actually transfer data off and on as with the stock Nexus.
I really enjoy this tablet and it fits my needs. Will probably upgrade to the new 8 inch acer tablet in a few months, since it has both front and rear camera and also an HDMI port.Just to clarify: Of course you need a micro hdmi to HDMI adapter cable to use the tablet with your tv and of course your tv has to have an HDMI in port.
I have been accused of writing a "wall of words" in other reviews under a different name, so I will give it to you in a nutshell in the first sentence of my opinion. If you read on, don't blame me if you fall asleep.The Acer A110's text and pictures are less sharp and somewhat fuzzy and the brightness, colors and viewing angles aren't as nice as on the Nexus 7.I really wanted to like this Acer tablet because of the HDMI out and the SD card slot.
Answer: I use my Windows Explorer while A110 is cabled to USB on laptop so I can use laptop keyboard and change what I want on MicroSD because the SD slot on my laptop no longer works...
