Our iMac intel arrived this afternoon and we quickly unpacked it and set it up.
It’s a 1.83 GHz 17″ iMac intel with 512 MB of RAM. Just the stock low-end machine.
Initial boot-up was slow, but every boot-up after the first has been very quick. Using Front Row is actually pleasurable. Garageband runs like stink 
Doom 3 runs okay. Halo runs great. Photoshop is a little sluggish but performance is not bad – the issue being that the areas where it is sluggish are not expected. Office runs fine on it – which is to be expected.
We have had one hard crash when unmounting AFP shares in the Finder. We’ll have to keep an eye on that. I don’t know what caused it. The server it was attaching to was a laptop on wireless so who knows.
Overall, it’s quite a fun machine. It’s very very light, it’s really quite sexy and in the short time we had it out in the office, it attracted quite a bit of attention.
It does make me want a MacBook Pro even more…oh yes, it will be mine.
