Okay, so I've had the 1.83 intel mac mini for a couple of nights now, and here are some of first impressions for those of you that care
Setup: stock 1.83 mini, wireless apple keyboard, wireless might mouse, Samsung 400P LCD via DVI, Yamaha 800 sound bar...
Graphics are great... native resolution is fine for viewing purposes from about 3.5m away, no eye-strain on the forum and web text.
Ripped DVD's via front row are surprisingly good. I rip to max 640 pixels wide... same res as the apple store and its very close to the same quality as the dvd... 720p hd video will look amazing.
Niggle... with a optical cable linking the mini audio out to the 5.1 sound bar amp you loose the ability to control system volume using the keyboard controls. THis may be peculiar to the yamaha, but its a pain... you gotta use the amp remote to change volume
512 RAM is not enough... all macs hould ship with min. 1GB standard... I'll be upgrading this little box to 2GB the first chance I get.
Airport: range and signal is excellent... full signal even through closed doors. Minor stuttering on streaming video playback that can be attributed to the router taking strain. Bluetooth works as if the devices were tethered.
Potential irritant is the fan noise... significantly louder than the G4 mini, fan seems to be running all the time

. Sounds like about 25-27db, but not as loud as the crickets outside the window... barely noticeable during movie playback.... perceptable during movies when at full tilt, sounds like about 29-31db?
Windows in a parallels VM installed first time no problems. Full screen performance was passable, but extra ram is going to be needed if you going to load lots of apps in OS X and MS at the same time.
Speed increase over the G4 1.5 mac mini feels like about 2x, performance feels about 0.8-0.9x the MBP 2.16 15" based on setiboinc and dvd ripping performance.
Overall: Definite buy. You can't go wrong with this box as a multi-media unit if you don't care to wait for the iTV. 4.5 out of 5
