Strengths: Nice viewing screen, Leather case keeps it safe from scratches, and is easy and fast to use.
Weaknesses: You can't buy a regular charger. I did'nt have the dock and months after the battery died I found out you could use your USB cable on a PC to charge it.
Bottom Line:
I love this little viewer It is easier than carrying envelopes of pictures and is smaller than a camera with (in most cases) has a bigger screen.
