I got into all things Blu Nov 08 and have been steadily building up a nice collection, which currently stands at 105. But I have put the brakes on now (credit crunch and all that).
Since getting the BD55 I have not purchased any more SD DVD's, in fact I have sold over 300 from my collection.
To be honest it not the picture that's totally blowing me away, its actually the soundtracks and especially DTS-HD MA

I know some don't hear much difference, but I can certainly hear it (and I would guess my neighbours can too at times)
Between now and the end of March there are around 30 Blu-ray titles that I am interested in. To buy them all would cost a small fortune, some might end up keepers and many would have to be sold at a loss on here (or a possible profit on eBay)
So just this week I have signed up to LOVEFiLM's 90 day free trial and added all those titles to my rental list. My trial won't end till towards the end of April. When this trial is over, I will look at other online rental outlets for free trials and there is even supposed to be a way of getting another free trial with LOVEFiLM.
Saving myself a tidy sum of money and if any of these titles BLOW me away, then I will wait for a bargain on said title and purchase later
There are however certain titles that will be day one purchases for me, if and when they see the light of day on Blu.
Star Wars
LOTR Trilogy
Jurassic Park + Lost World
Jaws + Jaws 2
Gladiator
Indiana Jones Trilogy
Alien Trilogy
To name but a few.....
So what are your Blu-ray habits these days?
