Probably some would be terribly jealous! My LO is 6 weeks today, and she does sleep a ton still. Like your guy, She's awake and active between feedings, but is only usually not fussy for between 45-60 minutes right now, so I feel like all she does is sleep. Got up around 530 this morning, was up for an hour, slept 630-830, was up about an hour and then slept 930-12, was up til 1 and now has been sleeping since.
Moral of the story, there are definitely babies just like yours who sleep a ton (mine does!), but there are other who hardly sleep (My SIL has one of those!). So I would say as long as you think he's healthy, you are fine!
