Ultrabook for simple Blender tasks

Hi everybody,

I’m planning to buy an ultrabook to take with me to the university. Aside from the basic stuff, I plan on using it also for some modeling and maybe animation in Blender. I’m definitely not going to use it for rendering or more complex and resource demanding tasks. I came upon these two options, but I’m not sure about which one I should pick:

Acer E3-111-P6WW (~U$338)
Intel Pentium N3530 (2.16GHz/2.58GHz w/ Intel® Burst), , 4GB DDR3L memory - 500GB HDD - 11.6" HD widescreen

(It’s the same as the one in the link, but without Windows 8: http://us.acer.com/ac/en/US/content/model/NX.MNTAA.004 )

Lenovo S210 (~U$415)
Intel i3-3217U (2 Cores, 4 Threads, 1.80GHz), 4.0GB DDR3L SDRAM 1600 MHz, 500GB HDD - 11.6" HD widescreen


The Lenovo is ~U$77 dollars more expensive. From what I have researched, the integrated GPU on the Acer is much worse than the one on the Lenovo, but the CPU on the Acer seems to be better when considering all the cores, but when considering individual cores, the Lenovo is better (but the difference isn’t that big in both cases). I’m also afraid of the heat dissipation on the Acer, since it’s fanless.

What do you think, is the extra U$77 worth it to get the Lenovo? Would the better GPU make the viewport more responsive? Could the Acer get too hot, even doing basic stuff, since it’s fanless?

Thank you in advance.
