I just picked up mine as well, I'm really liking having the physical keyboard again.
First thing I noticed is how quickly the phone boots. Seems like about half the time it takes the evo to boot.
I like the setup of the homescreens, the samsung widgets are pretty cool. Not quite as nice the sense widgets, but I'm not a big fan of the sense ui so the touchwiz is a nice alternative [id much rather have it vanilla though]
This thing flies, I didn't have horrible lag with the evo but there is certainly a noticeable difference between the 2.
Screen is a bit more clear, not by much though and I would be lying if I didn't say that I miss the extra real estate on the evo. Fat fingers like bigger screens.
My battery was dead out of the box too. Sucks but I just had to throw it on the charger for a while.
Overall I really like the epic a lot. I also like the evo a lot. But I think ultimately having the choice of a hardware or software keyboard on the epic will be my decision maker.
