It seems that now is actually a pretty bad time to buy a Blu-ray player. Prices are going up due to the lack of competition from HD DVD and no existing players are yet "Profile 2.0" compatible (which adds internet connection capability and larger local storage to the features offered by the current generation of "Profile 1.1" players). There's also talk about current Blu-ray titles being re-released with advanced profile features at a later date.
I could buy a Playstation 3, which is the only current Blu-ray player which will be upgradeable to Profile 2.0 with just a software update. It's also relatively cheap, particularly when you consider it can play games too. But navigating the menus with a game controller seems a bit naff and besides, I harbour a pathological hatred for consoles of all varieties, PC gaming snob that I am.
So waiting seems like the most sensible option, albeit the most dull.
