Recently took delivery of two F77s (both classic/zinc, one beige, one black). The black looks SO good in person. Beige also looks good but mine does have some imperfections in the powdercoating (one minor chip already visible out-of-the-box, some sections look shiny while others look dull, some areas have an especially noticeably thin layer/application, etc.).
Overall, however, I'm a very happy camper. The actual key action is fantastic. These keyboards are works of art, and the love and attention to detail that Ellipse poured into the project tangibly oozes out of every part. I am truly in awe.
Now time to sink my teeth into QMK.
After only spending a little time with them, I'll observe that one (IMO) flaw in the classic case design is how the bottom lip of the case is more squared off (even relative to other parts of the case), which I find causes it dig into one's palms slightly and makes it more uncomfortable than it really needs to be. But IBM came up with this design, and this was intended to be a faithful recreation of that design, so this is in no way Ellipse's "fault" (if it can even be called that). I personally think IBM should have made the original 4704 keyboards with a bottom lip curve of at least the same radius as the curves on the other 3 wide edges of the case.
I did take a Model M and line it up with the F77 on a flat surface to compare the side profiles of both, and confirmed that all of the keys on the rows that they have in common with each other are at exactly identical heights & that the backplates between both have identical curvatures. So though the keys on the F77 are in fact *not* actually higher than they are on the M, they *seem* slightly higher just due to the difference in heights between the bottom edges of the respective cases, and the M is just that much more comfortable to type on due to the bottom edge of its case sitting even lower & the gentler curve of that bottom edge on the M.
I haven't had time yet to really use it at length, so this may not end up proving to be that big of a deal long-term in actual use. And I can probably put some kind of sloped wrist rest immediately below the keyboard to help compensate anyway.
One thing I'd love to see is a visual comparison of the side profiles of the classic vs. ultra compact 'boards, which I don't think any photos I've seen to-date has attempted to show. I'd never seen an original 4704 'board in person, and just looking at the pictures before ordering, given its boxy design, I was concerned that the ultra compact would actually suffer from this very problem while the classic case *wouldn't*, because the bottom edge of the classic case *appeared* to be lower than that of the ultra compact. As a result, I decided not to order any ultra compacts. I'm wondering, though, if this is merely an optical illusion due to the fact that the classic case is lower just below the bottom row of keys than the back of the case is. Are the key heights between the classic and ultra compact in fact exactly identical?
EDIT: Now that I've got the keyboard set up in a more, uh...ergonomically-acceptable & permanent space, I'm finding that this is MUUUUCH less of a problem than initial testing led me to believe.
No discomfort to speak of. Would still be interested in seeing a comparison between the classic and ultra-compact cases from an ergonomics perspective.
