I was not able to put a SIM in it since I was told "not to do so". But I had my 8820 right beside me to compare it, and the Bold is a tad bit wider, the screen is what's the winner here, it was just so crisp and bright and flush, and beautiful. The keys are flatter, but the layout is similar to 88xx not 83xx. I hated the 83xx keys and loved 88xx keys and as you can tell, instantly fell in love with the Bold's keys. Definitely heavier than both (for obvious reasons). I can see almost everyone from the current userbase switching over to the Bold once it's out (Which I dont know, but I'm told is end of June for Rogers/Early july).
Also, this was a pre-production unit (no branding, nothing) but it felt solid, and the metal sides were definitely plastic, but it's solidly built. Also, because the screen is entire flush side to side, I dont forsee any "dust got under my screen" problems with this baby.
Dont ask me for pics, as I was not able to take them.
