I thought it'd been shown that the latest iMacs are not using notebook parts. Mac mini, yes, absolutely.
The only iMac parts that aren't notebook in origin are the display and hard drive. For months there has been discussion that the iMac can't go quad core because notebook quad core chips are too expensive and even the low power desktop ones are too hot for such a thin enclosure.
If the iMac doesn't go quad core, however, their so-called desktop line becomes an even bigger joke than it is today. As I stated earlier the reason to buy a desktop in the first place is to get more power and storage capacity than is possible in a notebook. The current iMac has a faster CPU than most laptops, but the GPU is ancient and even though they use 3.5" hard drives they offer no more stock storage than you'd get with a PC laptop. If you could easily get to the hard drive to put in a larger one it wouldn't matter too much, but to upgrade the HD in an iMac means taking off the glass cover, removing the LCD panel and digging around inside.
To the person who replied to my "the iMac is a 2008 era notebook" comment, you obviously didn't get the point. A 2008 era notebook doesn't begin to compare with a 2008 era desktop in performance/dollar. $1000 in a PC desktop compares favorably with the $2800 Mac Pro. The iMac isn't even in that race.
Apple doesn't sell a true desktop computer with significantly higher specs per dollar than a notebook. That's why people are buying MacBooks or coming here and bitching.
Dream: (1) merge the mini and the AppleTV into a single product with optional external optical drive and HDMI output - most minis are already running as headless servers or attached to TVs; (2) replace the mini with a mini tower.
Apple should look at what Dell, Acer, HP, etc. sell in the $499-999 range, equip their mini-tower with the same basic specs and options and sell it for $749-1499. Psystar, PearC and even most private hackintosh projects would disappear overnight because notebook sales have proven that Apple customers are willing to pay a 50% price premium to get a real Apple computer with MacOS X.
Of course that's just a dream. If the next iMac has a quad core CPU, a modern GPU, FireWire 800 and an accessible hard drive that'll probably be enough to persuade me. Glossy displays tend to over-saturate colors, but my family snapshots don't have to be perfect. I'd like it to have eSATA because it's both faster and less expensive than FW800, but that's about as likely as Apple making a mini tower.
Getting back to the topic, I hope this means new LED backlit iMacs and Cinema displays are just around the corner.
