Welp... Got Notes 7.02 today.
Visually, it looks "fatter". The fonts are more substantial. Almost bold in look. It also looks more "modern" if you will.. or more "mac-like".
The installer actually uses the default OS X installer. That's nice.
The whole BS "Lotus Notes" directory with all it's turds is replaced by a nice Notes.app applicaiton bundle. That's nice.
They added Safari as an option for URL handlers. That's nice.
It upgraded 6.5.x just fine, though I had moved my data directory to my home directory a while back, not sure (yet) how the upgrade will go if one's data directory still exists in the app's hierarchy.
It IS a Universal Binary! WooHoo!! That's REALLY nice!
It's still a carbon app. That's NOT nice. You'll notice the old MacOS watch icon. A sure sign of a carbonized app.
It still uses BinHex 4.0 as the default Mac attachment encoder. That's NOT nice.
I don't know how it handles emails with embeded java or HTML (I'm sure other users have experienced Notes crashes when reading some emails with HTML in them). Wait and see on that one.
It seems to be a bit faster, despite being a carbon app still. Wait and see on that one.
