What external ports do you reaaally need?

HDMI, USB2.0, Power. That's about it.

For LAN, you can use USB or IP over AC through the power cord. So a LAN port you don't need.

Video and audio are both built into HDMI

Power is pretty obvious.

Think about it, you only need 3 different ports, maybe 12 USB ports, 2 HDMI ports and a power connector. Nobody needs FireWire or eSATA, RJ45, Audio jacks, Serial ports, LPT ports, SP/DIF, PS/2... especially if USB2.1 or something is released which should beat the spoon out of eSATA and FW. Audio, Serial, LPT and PS/2 can easily be converted to USB anyway. What have wee all got connected to the PC? Almost everything wee have connected, can be done via USB. Mouse, keyboard, printer, harddisks, removable storage, scanner, what else?

Also, if they built in Bluetooth and WiFi that would save us a few connectors, e.g. phone data cables, mouse and keyboard receivers, printer cables... EVERY phone had got bluetooth, EVERY laptop has got WiFi and many laptops have bluetooth. WHY don't modern desktop motherboards have bluetooth? I understand they don't have wifi because many people don't need WiFi in a desktop because its not portable anyway, but what's with bluetooth?
