iPAQ 3900 Series Pocket PCs were the third generation of
iPAQs and the first to feature
XScale processors. Aesthetically similar to
the iPAQ 3800 series, the iPAQ h3950 and h3970
were also the last iPAQs to carry the Compaq
addition to being powered by the 400MHz XScale
processor from Intel, the iPAQ 3900s featured
an SDIO slot. Another
improvement that made the 3900 series a hit was
its front-lit screen, called a transreflective,
or transflective, TFT. Transreflective screens
are brighter and crisper than reflective displays
and make viewing easier on the eyes in both
indoor and outdoor lighting conditions. A new
IR port with increased range was used in
the 3900s for better universal remote functionality.
The iPAQ 3970 differs from the 3950 in two ways.
First, it has 48MB of Flash ROM for larger future
OS upgrades and a larger file store. Second, it
has onboard Bluetooth
capabilities like the 3870.
