The conclusion of XO-1.5 being nearly 2.5 times faster than the XO-1 could
be verified by comparing their hardware specifications.
at http://en.wikipedia.org/wiki/OLPC_XO-1  (For XO-1) and
http://wiki.laptop.org/go/Hardware_specification_1.5 (For XO-1.5) .Also we
can see the test results of James'(quozl) at
http://bugs.sugarlabs.org/ticket/245 which suggests that XO-1.5 is atleast
twice as fast as XO-1.

I also agree on the point that we should not rely on a vague idea of a
faster XO-1.5 than an XO-1 to judge the delay accordingly.
But still since the XO-1.5 is much faster than XO-1 , and also the issue
relates to rendering of an icon which relates to a graphic processing
ability , so we are bound to get better(if not 2.5 times better) results on
an XO-1.5.
