I don't think that's a problem in the next generation of tablets, as it isn't a problem on an old desktop with semi decent hardware acceleration (at least under linux, under windows I don't know, I'm still using windows xp with the classic skin, teletubbies stopped to amuse me a long time ago), the problem is that they will slow you down.
Not an issue if you can turn them off (as my kde desktop allows me to do).
