Update: And Samsung's confirmed this one for us. It indeed has a micro SIM card.
Now this is a bit interesting. According to this little tidbit that just hit our inbox, Verizon's upcoming LTE version of the Samsung Galaxy Tab 10.1 will feature a micro SIM card, and not a full size SIM card as found in the HTC ThunderBolt, Samsung Droid Charge or LG Revolution. That's not a huge deal, necessarily, though it does mean you're not going to be swapping your SIM card from device to device without an adapter.
It looks like Verizon will begin to introduce the micro SIM card later this month, though it's unknown if the Galaxy Tab 10.1 LTE will launch at the same time. It's currently available for preorder at $529 for the 16GB version, or $629 for the 32GB version.
Our next question is this: Will future LTE devices use micro SIM cards? Or is the Galaxy Tab 10.1 LTE a special case? News at 11.
