I think, that most people view dialpad in 9 keys, In fact all people perceive dialer in 9 rectangles. I am trying to explain, that nobody will think about it. Ask your colleagues. It 'just' a design. Dateless design. Sorry for my poor english.
#194 is the leading choice right now. We agree, 9 buttons seems to be the right choice. Can you make some additional modifications to it to make it closer to the colors and feel of #299? I'm finding myself drawn to #299 based only on the colors and how it resembles the Salesforce logo:
I'll place you in spot #1 sometime late on Wednesday to allow you to upload your changes. Thanks! We like how easy your EPS will be to modify as our business changes.
#348 is nice. Any way to give it a 3d feel? Otherwise it's close enough that we can modify the image afterwords. Number #299 still has a feeling of being a chip or something with a bit of thickness to it. I'd like to give your buttons a little depth like that. But we still love what you have done, so don't stress over it.
I tried to add light 3d feel to my designs, but I think that 3d feel is not good for that simple logo. Strong 3D effects can ruin visibility of R and D in the dialpad. That's my opinion. Strongest design is the simply one.
