It's kind of hard to go wrong here. There are few awful 28s out there.
I think the 28 was a wise choice. It wouldn't surprise me at all to see you wanting a 24 in a few months, but the 28 is so inexpensive that even if you end up with a 24, the 28 will earn its keep regardless.
I've occasionally been tempted to get a 28/3.5 as a throw-around lens (Nikon had a pretty good one too), but so far I've resisted.

A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.
