Well, no longer. Because Apple (AAPL) is planning to refresh its iMac desktop computer in the next few weeks, and when it does, it may well offer a Blue-ray drive option.

Sources tell AppleInsider that the new all-in-one, dual-core desktops, which are also said to feature a new, slimmer enclosure, were finalized earlier this month and are already rolling off the assembly lines of Apple’s manufacturing partners.

“The late 2009 iMac line should also debut several features previously unavailable to Mac buyers,” the publication notes. “People familiar with Apple’s thinking have suggested in recent months one of these moves could see the company finally embrace Blu-ray.”

One last point worth noting here: According to the MacRumors Buyer’s Guide, the iMac is due for a refresh. Apple has updated it every 220 days on average since it debuted the machine in 2003. As of today, it has been 204 days since the last update. MacRumors’s recommendation: “Buy only if you need it–Approaching the end of a cycle.”

One of the investments we make is to introduce new products that initially cost more because they deliver an entirely new level of value to the customer. Then we ride the cost curves down with value engineering and volume manufacturing, leaving us far head of our competitors. We have some of these types of investments in front of us that I can’t discuss.”

The media will gather tomorrow at Apple’s Cupertino, Calif., headquarters for an invitation-only event–presumably about updates to its MacBook and MacBook Pro lines. And as with every Apple (AAPL) product launch, tomorrow’s has been preceded by feverish speculation about what form, exactly, those updates will take. Among the rumors currently making the rounds:

• Apple will uncrate a new line of MacBooks whose cases are carved from a single brick of aircraft-grade aluminum.
• Apple’s refreshed MacBook line will include a machine priced at below $1000, perhaps even as low as $800.
• The new MacBooks will feature glass, multi-touch trackpads and LED-backlit displays.
• They’ll swap out Intel’s chipset–not the central processor–for Nvidia’s MCP7A, which reportedly blows the doors off Intel’s G45 in the graphics department.
• Blu-ray will be offered as an option on high-end models.
• Finally, Apple’s new line of portables will include the unmatchable “state-of-the-art new product” to which Apple CFO Peter Oppenheimer and COO Tim Cook referred earlier this year, and that product will be a tablet. Something along the lines of the “MacBook Touch” described by MacDailyNews back in July.
  

  Think MacBook screen, possibly a bit smaller, in glass with iPhone-like but fuller-featured multi-touch. Gesture library. Full Mac OS X. This is why they bought P.A. Semi. Possibly with Immersion’s haptic tech. Slot-loading SuperDrive. Accelerometer. GPS. … App Store-compatible, able to run Mac apps, too.”

An interesting spread of rumors, some quite likely, others improbable … and yet entirely plausible because, after all, it’s Apple we’re talking about. We’ll find out which of these proves true tomorrow at 10 a.m. PDT. I’ll be covering the event live, so be sure pay us a visit tomorrow.

In an announcement reaffirming the device’s pricing (from $199 for 8GB to $299 for 16GB to eligible customers), AT&T said it will sell the iPhone 3G without a contract for $599 (8GB) or $699 (16GB). When? “In the future.”

AT&T will begin peddling the iPhone 3G at its retail stores beginning July 11 at 8 a.m. local time, along with bundled voice and unlimited data plans ranging from $69.99 to $129.99 a month. The company’s posted a handy 3G coverage viewer here.
