I think you guys are going a little nuts with these laptop requirements. Basically as long as it runs Windows, you're cool.
DrHobie,
Thanks. I won't pay much attention to the details.
For those who are curious:
Portable Computer Cards (PC cards) are interchangeable peripherals designed to be inserted into laptop computers in order to enable extra hardware functions. Such cards include (but are not limited to) flash memory, modems, network interface cards, and SCSI disk controllers.
They were first called PCMCIA cards as the original standards were set by the Personal Computer Memory Card International Association.
The PCMCIA has developed a new notebook peripheral specification called ExpressCard.
The first PC cards (PCMCIA, with the more logical IBM meaning: Peripheral Component Microchannel Interconnect Architecture) were Type I, and supported actual Memory Cards (e.g. Linear or ATA Type I Flash Memory Cards), such as SRAM or flash memories. Type II cards added I/O support in addition to memory applications, and type III expanded functionality. The interface's role as I/O for various devices has largely superseded its role as a Memory Card, but this role did spawn a generation of flash memory cards that set out to improve on the size and features of ATA Type I cards (CompactFlash, MiniCard and SmartMedia).
ExpressCard is a hardware standard replacing CardBus, both developed by the PCMCIA.
The major benefit of ExpressCard technology over the previous PCMCIA CardBus PC card is the major increase in bandwidth, as the ExpressCard has a maximum throughput of 500 MBps two-way communications versus CardBus' 132 MBps. This large increase is afforded by the fact that the ExpressCard has a direct connection to the system bus over a PCI Express x1 lane or USB 2.0, whereas CardBus utilizes an interface controller that only interfaces with PCI. In addition,
the ExpressCard standard uses lower voltages and thus less power than the previous CardBus slots (1.5V and 3.3V versus 3.3V and 5.0V). I think that's why lighter, more mobile laptops only have the express card slots.
