I just picked up my new Silver MBP 13" base model at the Apple Store this evening and I agree with everything you have said. The size and weight feels about the same as my old 13" MBA and the form factor is great. The new keyboard is a MASSIVE improvement over the keyboard on the rMB and is one of my favorite parts of the new MBP.
Rather than deal with the smudges and scratches on the Space Grey (which I have on my rMB) I decided to go with classic silver and am very happy with the way it looks.
The screen is amazing...bright, crystal clear, amazing blacks, super sharp and great color.
The speakers are loud and full-sounding with good bass and nice stereo separation...very enjoyable to listen to
Thanks for sharing your thoughts!
