Soo, today I got a few extras I found at various sites. First an extra Samsung battery. I do have some extra external chargers but in reality an extra battery really doesn't take up too much space and you don't have to wait for it to charge once you discover you are out of juice.
I also got a table stand/dock charger. Turns out that this is a great stand for the K3 as well. You can put it in there if you want to have your hands free while reading, and you get it charged while reading as well. Two stones a bird, ant all that.
I also got a nice case for it, a leather case that can also function as a stand for landscape mode and it even has room for two credit cards and some bills. In essence i can leave home with just one little thing in my pocket now.
