I got my 24" iMac today and thought I would write a little.
2Gb, 2.16GHz, 7600GT - all else standard.
Upgrading from a 17" 1.6Ghz G5 iMac, which I sold a few weeks ago. Have been using my 1GHz TiBook in the meantime.
This is the first Apple machine I have owned from new. Previous machines have been refurbs or from eBay.
Packing was slimmer and more robust than my 17" iMac.
The powercord which plugs in flush with the back of the machine and does not have a little plastic ring loose on it was nice to see - always annoyed me on the G5.
I am not using the included Might Mouse - it would not right-click whilst I had my left finger resting on the case. Besides, I prefer the big scroll wheel of my Intellimouse as well as the shape of it in my hand.
Copied over my music, photos, documents and archives by Firewire. Didn't use the Migration Assistant as I wanted to get all my applications "new" and in Universal format. Also copied over my Adium, Mail data, Safari bookmarks, my keychains etc manually.
Copied over my games then patched to UB, rather than reinstall.
Set up my mouse/shortcuts/prefs/add-ons. Shame that WindowShadeX is not fully UB yet, since I paid for it ages ago.
At this point, my housemate came into my room and collapsed on the floor laughing at the sheer size of it then said she was jealous. I went to make some lunch and came back to find she had taken about 8324728347 pictures of herself in Photobooth.
We then played around with the remote control, which is the first time I have ever used it. Really very cool indeed, especially the little effects and noises.
I then started to install Bootcamp and XP, at which point my housemate got very bored and left. Took about 35 minutes in total, with no problems. Didn't really do anything with XP though. Just wanted to install it in case I need it. I will probably play MapleStory or something at some point.
I'm very impressed with the machine. A definite improvement in speed and functionality over the G5 and G4 machines I had/have. The screen is simply brilliant. I used iChat for voice and video for the first time and it was like being on the phone. UT2004 at max resolution with everything set to Highest just flew around too fast for me to even play properly - a bit too used to slowing myself down. WoW was amazing too - around 60FPS with everything turned on. Looking forward to levelling my hunter a bit after work.
The internal speakers are very good also - I have external Yamaha ones but am not using them any more.
Despite the size, the machine feels light yet sturdy.
So far I am extremely happy with the purchase and would recommend the 24" iMac to anyone who is considering it.
