I'll assume you mean the two models of laptops, and not the processors that I
linked.
Why, then, is there no numeric keypad shown in the head-on photograph of the
King Penguin on its page? Or in the photograph from the right in which the
other side of the keyboard is barely visible? Do you have another photograph
of the model that would prove what you say?
I still don't think those features are worth $274, and not knowing how long
the sale will last I can't guarantee I'll make the purchase before it ends.
What do you mean, "a significant difference"? Here's a full comparison of the
models as I would purchase them:
Screen — 15.6" Matte 1920 × 1080
Dimensions — King Penguin 14.73" × 9.92" × 0.55" ~ 1", Gazelle
Professional 14.72" × 9.92" × 0.55" ~ 1.24"
CPU — King Penguin Quad-Core i7-3630QM 2.4-3.4GHz, Gazelle Professional
Quad-Core i7-4700MQ 2.4-3.4GHz (comparison linked in my previous comment;
they're almost identical)
Memory — 16GB DDR3
Graphics — Intel HD Graphics (4000 King Penguin, 4600 Gazelle
Professional)
Hard drive — 500GB HDD (I'm also considering a hybrid for the King
Penguin)
All further differences are purely appearance-related. I made an error in the
previous comment. The Gazelle actually has four USB ports; three are normal
and one is an eSATA hybrid. One more advantage vanishes. Also, the Gazelle
includes a memory card reader. One more advantage appears.
