Haven't actually bought MC yet but have been playing Classic. I want to buy MC (and a new computer), so I tried the demo with my 5-year-old Macbook running XP in Bootcamp. It ran smoothly enough on the right settings, but I was getting no sound.
Trying to fix the sound problem, I've just updated Java (after removing the older version). Now the MC demo won't start at all, and I get this message:
Bad video card drivers!
-----------------------
Minecraft was unable to start because it failed to find an accelerated OpenGL mode.
This can usually be fixed by updating the video card drivers.

How come it worked (albeit without sound) before I upgraded to the latest Java?
Your graphics card has the minimum required support for opengl. To play the game, but for some reason, the launcher itself requires a higher version.. Perhaps they plan to make the game require a higher version in the future.
There are alternate launchers that allow people to play. Magic Launcher, and MultiMC. I don't believe either of those work with the demo version tho. Might not hurt to give them a try.
I use multimc, so have the link on hand for that one, your welcome to search out the other for yourself.
Thanks Hiding, but I wonder why the MC demo was working before I updated to the latest Java?
At mojang support I read that some people have problems using the latest version of Java. Well, what are we supposed to do? Even if I could find Java 6, wouldn't using it be a security risk of some sort? The Java I had before was called something like Java 6v2. I do remember having to update it or something a few weeks ago when there was some big Java scare in the media.
Well actually that java security risk is still present even in java 7.7 (the latest version)
It's in java 7.10 that it is to be fixed, and that's still in beta testing.
Honestly, I'm not sure why updating java would make the launcher no longer work. But I've seen in it a number of times over the last few weeks, that older cards couldn't run MC with the default launcher, but worked with multimc. It could be, that with the newer version of java, minecraft upgraded the lwjgl library included in minecraft,
I would agree with Hiding, although if I could put my 2 cents in, I had this problem on an older laptop but I solved it by playing in-browser instead of from a .exe or .app. For whatever reason Minecraft just didn't want to run outside of a browser. Hope that helped.

Thanks Pixel8ed, but I'm assuming you're talking about the paid-for version. I'm talking about the demo, which is also "played in the browser", is it not?
Jeez, I hope I don't have this kind of hassle when I get my new computer in a few days. It's just that I was hoping to use both my computers on a LAN...
