I also took my first-ever selfie, thus learning that using the camera on the same side of the smartphone as the screen gets you a mirror-imaged photograph. I left the selfie that way on my obligatory Facebook post for purposes of historical accuracy and as a cautionary tale, but it turns out to be quite easy to flip photos (both horizonally and vertically) from the Android Gallery app. It is also possible to change brightness and contrast, add captions, add simple graphics, scrawl over the photo in various colors, adjust perspective, and so on. An application popped up and offered much much much more (QR code scanning! OCR! Other stuff I didn't bother reading!), but only if I would agree to the license. Which I might do some time in the future.
I have not yet worked out how I will carry the smartphone long term. For the moment, it rests in the classic nerd position in my shirt pocket (truth in advertising!!!).
My wife was not all that impressed with the smartphone, which is not too surprising given that grade-school students commonly have them. She did note that if someone broke into it, they could be taking pictures of her without her knowledge. I quickly overcame that potential threat by turning the smartphone the other side up, so that any unauthorized photography would be confined to the inside of my shirt pocket. :-)
