"Like the e5000, the e4000 can be purchased with a 600MHz
Celeron or 1.4GHz Pentium M processor, and can be equipped with up
to 1GB of DDR SDRAM, says Glacier. The unit ships with a choice of
either a 10.4-, 12.1-, or 15-inch SVGA (800 x 600-pixel) LCD screen
with 5-wire resistive touchscreen. The display can be fitted with
an optional sunlight-readable display, as well as a novel heated
touchscreen that keeps the screen clear even when wheeled in and
out of a freezer, according to the company.
"The e4000's shock-protected 2.5-inch hard drive is available in
capacities starting at 40GB. Peripheral interfaces include an
Ethernet port, and two USB 2.0 ports, instead of the e5000's three
ports (it sacrifices the internal port), and a single serial port
instead of two. Audio I/O is provided, but not the e5000's VGA out
connector. The e4000 lacks its sibling's PCMCIA slot, but offers a
mini-PCI expansion slot. The other two omissions are the internal
backup battery and the "rotating drive," said the
spokesperson."
