Just got 4.0 today. Running on a 450 MHz P2 under W98.
Observations:
Interface is nice, but not a lot different.
Graphics (2D and 3D) come up noticeably faster
The bad news is that number crunching appears to be slower. I have an
application in which I take a potential function which is a function of R
and theta and expand it in terms of Legendre polynomials. To do this I do a
2D curve fit on the data and then use NIntegrate to get the Legendre
coefficients as a function of R. Here is the timing for two different
applications.

1 156s 197s
2 944s 1044s
At least 10% slower.
