The good thing with a PC notebook is that you get a usable touchpad

every time I sit in front of a Mac portable.
If you use the CTRL key instead of the ALT you will get also on a Mac
accessiblae menues when using the up or down arrows :-)
How to decide on a notebook? Sit in front of those you find
interesting (all with dedicated graphics, obviously) and pick the one
whose keyboard and screen you like the most. The differences on the
outside are bigger than those on the inside.
The dedicated graphics I assume is talking about x MB of VRAM. Recently
a lab member obtained "almost" the priciest fruit without dedicated RAM
a MacBook C2D (Core2 Duo, not to be mixed up by the revision A model
which is only CD). I thought this would be the bottleneck for the whole
system and it turns out that the Open GL test (from XBench) scores with
244.6 points versus my Revision A MacBook Pro also with 2 GB RAM and a
RadeonX1600 with 128 MB VRAM only 134.4 points. The overall Xbench score
for the MacBook C2D (2 GHz, 2GB RAM) is 105.53 points versus 75.64 for
the MacBookPro Revision A(1.83 GHz, 2GB RAM) model.
I therefore think you can't state that dedicated RAM is better.

Even though I am too cranky about my recent Apple laptop
experience to
recommend it to anyone other than the most annoying of enzymologists,
I will say that the integrated graphics card was one thing that
was better
than expected. It passes the pymol and coot tests with flying
colors,
which is great until the machine overheats and shuts down in the
middle of
a presentation.
