Yeah I would not consider Quest Spotlight a "monitoring" tool.
Meaning you can't go home and have Spotlight warn/alert you about free space...or locks.
It is for "active monitoring"...active diagnostics much in the way a DBA would actively (not constantly) query v$session, etc.
It puts "face" on the Oracle database.
Spotlight does a great job of pointing you in the right direction when you already know *something* is wrong...not telling you something is wrong ahead of time.
Spotlight is to much of a client PC hog to run it for more than several databases for a log time.

Regarding "face"...the GUI itself.  I have not seen the 10g "Dashboard", but I have a hard time, based on past experience believing that OEM has a better, more intuitive, and compete GUI than OEM.  Am I wrong?...is OEM 10g GUI that good...that changed.
I did hear the Oracle hired away many Quest Developers?

The 10g EM web interface is dreadful, utterly dreadful IMO. 2 links labelled the same on the same page for goodness sake that do different, though similar things. Sometimes the only clue that you ought to look at something is a tiny, tiny icon and so on. It's very very poor. The functionality is rather good actually, but sometimes I think they hired people with my web design skills or worse.
I can't comment on release 2.
