I've been in the market for a new iMac for a while (my G4 model is getting oooold), so I was excited about this week's new-iMac announcements.
One of the new 20-inchers just arrived here for review, and I mostly love it.
But choosing among the models -- some with 20-inch screens, others with 24-inch displays -- will take a bit of thought once I'm ready (soon) to plunk down money for my own computer. Some of the issues:
Display. I've just swapped out a Mac Pro review unit for the iMac, and I noticed right away that its shiny screen isn't nearly as nice as the slightly-more-subdued one on the Studio Display that came with the Mac tower. (the iMac screen is brighter.)
This is a glossy-vs.-matte, apples-vs.-oranges comparison, I know. But even so, the iMac's display has a slightly washed-out quality that is a bit disquieting. The screen on the 24-inch iMacs is nicer. This is the subject of a lawsuit.
In a call with Apple, it was made clear to me that the 24-inch iMac has an 8-bit display with millions of colors while the 20-incher has a 6-bit display that "blends colors into multiple shades, effectively getting millions of colors." Hmmm, that's not the same thing.
Speed. While all the iMacs have Intel's new,faster "Penryn" chips, the 24-inch iMacs are zippier than the 20-inchers. So forget about custom-configuring a 20-inch iMac with the 3.06-GHz Intel Core 2 Duo processors in highest-end 24-incher (also available in the next model down as a custom option).
Ditto for video; you can't put the high-end iMac's pumped-up NVIDIA GeForce 8800 GS card card into a lower-end iMac.
Apple has effectively sliced it's iMac lineup in two. This is not so great for customers, one tech blogger writes:
What I find really surprising is that there is an increasing gap between the 20" and 24" units...if you're in a space-constrained environment, you can't get the fastest unit. I can understand the need to differentiate products but surely a better customer outcome would have been 20" and 24" units with the same top specification. There's no option to upgrade the video card or processor in the 20" units.
Memory. Random-access memory from Apple used to be obscenely expensive, but the company has cut a 2-gigabyte upgrade on an iMac from about $400 to about $200. Just do a custom online order, and you're golden. That's the good news.
The bad news: You can still get memory for much, much less elsewhere.
But doing this is tricky because an iMac with a standard 2 gigabytes of memory has no open RAM slots. You have to pull out two 1-gig modules and replace them with two 2-gig ones. Then you're left with the original modules, for which you have to somehow find a home. (Is there a market for these things?)
Storage. Apple imposes a cascading series of storage ceilings on its iMacs. While you can get up to a terabyte of hard-drive space at the top of the line, the entry-level iMac only goes to 500 gigabytes and the next model up only goes to 750 gigs.
Sheesh, Apple, I wish iMac shopping were just a teeny bit easier. I don't want a big iMac, but I do want a souped-up smaller one to fit into my cramped working space. I can't get that.
