...the free app for 31 Dec 2011. But that's interesting enough to warrant still talking about it.
The app in question is Mahjong Solitaire. I always look at reviews before I download, and goodness this had a lot of negatives! So I started reading them. The first one was "I'm-a-computer-security-person" and went on about this app needing permission to open a network socket. "Only spyware needs to do that!"
...Wait. Opening a network socket is required to grab an add from the app store owner, push or pull notifications (like global scores), look for an update, see if it's a friend's move in a social game; in other words, TO DO ANYTHING NOT LOCALLY STORED IN THE APPLICATION. All these complaints when very, very popular apps, like Angry Birds, Where's My Water, Plants vs. Zombies, etc., etc. ALL REQUIRE PERMISSION TO OPEN NETWORK SOCKETS.
I was unimpressed with the argument. The game runs fine.
Part II of this, which I didn't realize until this morning:
So I was up late. I mean 2:45 late. Playing on the Kindle. I went to see if a new app was up in the free app of the day. Yes, there was, Mahjong Deluxe. I already had the free edition. Awesome! I installed the full one for free. I played a few boards, then the husband came to bed so I shut it off and went to sleep too.
Now, just as I was writing this, I went into the Amazon app store to double-check the free app of the day. It ISN'T Mahjong Deluxe. Hunh. I got an extra freebie! No complaints.
