I normally don't upgrade to the next series, but with trade-in,and pixel watch 2 deal I decided why not
While I didn't particularly love the curved P7P screen it did give you more desktop real estate. The 8s screen feels a tad squished in. Everything on screen is a bit smaller. I don't hate that but it's a surprise.
I just got my Peak Design case so I can use my PD mounts (motorcycle primarily). The case seems decent however, much like my opinion of the P7P case, I think it could use slightly more lip to protect the screen and camera bump. The screen lip is probably fine if you don't run a glass screen protector, adding that thickness really reduces the lip.
Otherwise, I have only really spent time setting it up, not much time using it yet :).
Living longer and rising in price.
