5 New IP Phones from Cisco

After looking at these phones a bit more, I'm shaking my head at some of the design choices.  I'm nitpicking, to be sure, but I still think they're valid criticisms from a usability and physical appearance standpoint.
 
The only phone out of the five whose line appearances line up with their respective buttons is the SPA501G, which is the 8-line-appearance phone without an LCD display (it uses a paper line-label insert).  Since it has no display, the phone has no soft keys, so the four soft-key buttons have been assigned to static functions.  I really don't have any particular complaints with the design of this phone, it seems straightforward.
 
However, the SPA502G, which is allegedly a two-line-appearance phone, has no line appearance buttons at all, and the SPA504G, SPA508G, and SPA509G all have somewhat wacky line appearance button layouts.  I'm imagining one can use the dirpad to bounce back and forth between the two lines, but I don't understand why Cisco didn't just slap two buttons on the phone next to the display.
 
The rest of the phones suffer from having the buttons offset from the physical appearances of the lines on the display, with no lines or grooves on the bezel leading from the buttons to their lines. I understand why it is the way that it is: the buttons are in the same place as they are on the SPA501G, which has no header or footer on its display, so on that phone, the buttons line up exactly with the lines.  By keeping the buttons in the same place, Cisco can use some of the same circuit boards between models to save on production costs.  But on those others, with the header and footer, the buttons no longer line up. But it's not like all the phones use the exact same bezel mold (look carefully, they're all different in at least one way), so I don't see why they didn't put grooves on the bezel for the SPA502G-SPA509, like they do on the Cisco 79xx series (and the Avaya 46xx series, for that matter). Note that the SPA525G has the same flaw.
 
What is up with the SPA509G, though? Did Cisco really slap four additional line appearance buttons below the softkeys in that bezel inset? It just looks awkward, and I wonder how awkward it is to use.
 
IMHO, to keep production costs and configuration complexity down, Cisco should have stuck with the SPA501G, SPA504G, and the SPA508G and skipped the SPA502G and the SPA509G completely.  The latter two are kind of odd men out, and I don't think that anyone who needs more than eight line appearances would have crowed too loudly about needing the SPA500S sidecar.  If anything, I would like to see a "SPA516G" that looks like SPA508G with a "page" button to switch between two virtual pages of eight buttons (a la the 7915/7916 sidecars).
 
Finally, I really would have liked to see a sidecar with an LCD display, in addition to the paper-label-insert SPA500S.

I did some usability with them. They're pretty cool.
