Re: I've had a look at this
I am also a user of Lightroom despite it being from Adobe. In fact it is one of the few things they have ever done that I would recommend. It is, in my opinion, an excellent piece of software. There are some things it lacks such as where iPhoto will keyword tag by key shortcut which would be very handy for family photos but it has consistently gotten better over the years and is multi-platform thereby not tying you to an OS.
I discovered it after Adobe bought out Pixmantic who owned RawShooter where some influences can be seen.
