Pioneers: Which ones had recessed LCDs, and which had flush/covered LCDs?

[rprosperi]

Obviously it's subjective, but most people (that I've discussed it with) tend to agree on these points (which you also note):

The flat/raised style tend to allow dust under the glass cover.

The recessed units tend to be easier to read/more clear, as there is no glare from the covering lens and 1 less layer to see through.

The recessed units are easier to read from the side (not straight above).

As for aesthetics, I like the looks of the recessed style much better, but other folks should share their comments.
