I expected a semi-round approach for the FR935 (as it can be considered a FR735xt successor), but looks like they went the round screen way of the Fenix5...
It is a Fenix 5 screen and internals inside a lighter weight plastic body. The plastic body allowed them to make it thinner and to use a more reliable and precise GPS antennae as well.
I think we need to wait until there's been some tracks recorded with the 935 until we make an assumption that the 'more reliable and precise GPS antennae' will work better than that in the F5. After all, this is only an F5 in a cheaper carcass. Some of the tracks recorded on the F5 are significantly worse than my 920.
