Between the two you listed the 11.6 ultra portable HP dm1-3025dx is a E-350 dual core CPU of the new AMD Fusion E series.
That Toshiba C655D is full size @ 15.6" but only has a single core E-240 Fusion CPU.

I don't favor the single core CPU. Toshiba Satellite C655D AMD E-240 Fusion APU Notebook Review
I couldn't find a matching review for the Pavilion dm1-3025dx but it should be just about powerful enough to do all that you want and perform reasonably well. It doesn't have a DVD drive at that size if that's important to you.
For comparison look at a Dell Inspiron 14R 14-inch Core i3 2.53GHz Laptop $450
It's Core i3-380 CPU has about 3 times the CPU power of the E-350
