Wolfram Alpha
With amazement I have just explored the following website at Wolfram, the makers of Mathematica.
For example you can give the following input:
     integrate exp(-x^2) x=-5..5
for the site to return pi^0.5 erf(5) = 1.7725, and it even gives a visual representation of the integral.
Other examples:
     1 hartree in eV
           Gives the correct conversion
           Gives all isomers and molecule weight
           Gives the definition
     plot x^2+y^2
           Gives a plot of this function
     fit {1,2,3,5,7,9,13,16,20}  
           Gives polynomal fits
     eigenvalues {{4,1},{2,-1}}
           Computes the eigenvalues and vectors
