"Windows CE also has a "low memory footprint and a good
collection of apps." NVIDIA is working closely with Microsoft to
improve Windows CE's performance on Tegra, NVIDIA's ARM platform.
Windows Mobile is also being worked on.
"Android, on the other hand, lags behind Windows CE in almost
all areas, according to NVIDIA. The interface is rough and not at
all ready for larger displays, and all video and graphics rendering
is currently done by Android's Java code, which is simply too slow
for HD video - something the Tegra platform handles just fine on
Windows CE."
