This is exactly where you will get if you're trying to massage the
Tegra2, MX53, OMAP4 into a high end laptop; it will not meet your
expectations. They are not designed for those environments. Tegra and
OMAP4 are phone/tablet chips almost entirely focused on Android. MX53
is for in-flight entertainment, Ford Sync, handheld media tablets,
that kind of thing. Remember when you think about speeds on devices,
they are always listed as maximums. Yes, SATA-II is 3Gbit/s (actually
about 2.4Gbit after you get past the 10-8 encoding) but does a device
need to run at that? Not at all. USB 480Mbit/s? Nope.
You can't design a system, keep it cheap and make it a volume seller
by just picking the chips with the biggest numbers.
The trick is, pick one component and select all other components as cheap as possible, but still not bottlenecking the whole system. I got rather small experience in System design, but if you intend to do so, get some money-monkey keeping an eye on the BOM and timeline.
Just my 2 cents.
