I sent this moments ago to the folks at Livescribe, who make an
electronic pen that I find quite amazing. See http://www.livescribe.com/
for more on this pen.

Dear Livescribe,
First and foremost, I am greatly pleased that you provided your
specifications in metric units. However, you have some errors that beg
correction and I provide some suggestions here. My background includes a
lot of involvement in developing and maintaining standards relating to
the metric system, which is known as the SI.
A classy product deserves a classy web page. A web page with errors
makes one wonder about the product.
Your page says:
Weight: 36 Grams (1.3 oz.)
The unit name should not start with an uppercase letter. You should
write this as "36 grams". Or you may write "36 g" instead, noting that
the symbol is not modified to indicate the plural. Technically, the
quantity is mass, not weight, but "weight" is commonly (mis)used instead
of "mass". This is outside the metric system, but there is no need for a
period following the symbol "oz" since it is a symbol and not an
abbreviation.
See:
SI Brochure at http://www.bipm.org/en/si/si_brochure/chapter5/
NIST SP 811 at http://physics.nist.gov/Pubs/SP811/sec08.html#8.3
Your page says:
300 mAH rechargeable lithium (non-removable)
The symbol for hour is "h", not "H". In the SI, "H" is the symbol for
the henry and I am certain you do not mean milliampere henries. Thus write:
300 mAh rechargeable lithium (non-removable)
See:
SI Brochure at http://www.bipm.org/en/si/si_brochure/chapter4/table6.html
NIST SP 811 at http://physics.nist.gov/Pubs/SP811/sec05.html#5.1.1
Spaces should appear between numbers and unit symbols. Thus write
Length: 155 mm (6.1 in) instead of "Length: 155mm (6.1 in.)". Note again
that there is no period after the symbol "in". Likewise write:
Width: 14 mm or 0.55 in (bottom) to 16 mm or 0.63 in (top)

Your memory specifications indicate gigabytes (GB). I question this. Do
you really mean 10^9 bytes or do you mean 1024^3 bytes? that is, are the
two sizes of memory 1 000 000 000 bytes and 2 000 000 000 bytes or are
they 1 073 741 824 bytes and 2 147 483 648 bytes? If the former, then write:
1 GB and 2 GB
If the latter, then write:
1 GiB and 2 GiB
where Gi is the prefix for the binary multiple 1024^3.
