The base model Intel MacBook comes with 24-bit 96kHz audio inputs/outputs, both analog and digital, directly integrated with the OS and with very low latency (processing time). It has Firewire 400 on the motherboard, see above, which is the most popular way to add an external audio interface. It has an excellent high resolution screen and directly supports a second monitor up to, say, 23" for dual screen operation. It comes free with a quality Audio/MIDI editing application (Garageband) stuffed with better than average virtual instruments and a fully functional Video editing app (iMovie), both directly compatible with FinalCut and Logic Pro, leaders in their respective fields. You can buy it for $949 (plus another $70 or so for an extra 1GB RAM. easy to install and not optional IMO) from any Apple store where it can be returned to an intelligent human if a problem should arise and often be fixed on the spot.
It's also the coolest looking hardware on the block. And runs WinXP if you feel the need.
Ummm...get me a laptop like that for $500 from Dell? I think not.
N.B. I don't work for Apple! I just need to work with quality hardware.
Nother N.B. - not an advert, but I run my MacBook with a Samsung 215TW 21" 16x10 monitor when editing. Beautiful 1680x1050 widescreen display. rotates to portrait mode, Analog & Digital computer inputs, Component, S-Video & composite analog video inputs, small tinny speaker (but OK for video monitoring) Does analog video picture-in-picture while displaying the DVI-D computer input - amazing when editing video or writing to picture. Looks _almost_ as nice as my Apple 30" at work, costs $450. ***?
