Upgraded from my D60 to a D7100 thanks to Boxing Day sales (couple weeks late posting, admittedly).
Also got myself two 32GB SD cards that can keep up with the shooting speed compared to my old, slow 16GB cards which.. were still faster then the D60...
And time for the classic cell phone picture when I clearly have two cameras.... don't even feel bad about it.
So far so good, thoroughly enjoy the shooting speed. The 1.3x crop mode is interesting, likely will only see limited use.
Still getting use to the dual selector wheels and where all the buttons are and what they do. It's a fair bit different from the D60 which I could do without looking (I even had the LCD menu system down to memory, totally different now).
The dual SD card slots is nice, so I don't have to splurge for 64GB cards, I can get the relatively cheap 32GB cards and hold 1700ish RAW photo's in DX, or 2600ish in 1.3x crop.
Haven't tried the video recording yet, probably won't for a bit, I rarely, if ever, record anything (the things I would I'd borrow a friends GoPro/Sony ActionCam).
