"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."
