You gotta love rumors confirmed. Mac OS Rumors started combing the grapevine and all their sources clean of whatever juice they could squeeze out, until they were able to confirm that the "MacBook Thin" (a) exists, and (b) has specs that (c) would probably make the "Thin" "the fastest, most feature-rich ultraportable laptop on the market". Probably because it's a Pro in a smaller package.

Here are the specs that Mac OS Rumors were, so far, able to confirm from American and Southeast Asian sources. Start drooling.

• "Macbook Thin" -- spec-wise, primarily a variant of the Pro family but will probably be branded as separate from the standard *or* Pro MacBook families. Shipping name is unconfirmed.
• 12-inch widescreen display, 1280x800 resolution.
• 2.16 or 2.33GHz Intel Core 2 Duo processors
• 1GB of DDR2-667 memory standard. Max. capacity 3GB.
• Standard "Pro" ports: USB2, Firewire 400 & 800, Gigabit Ethernet, Digital/Analog Audio minijack I/O ports.
• ExpressCard expansion slot (believed to be /34 type)
• Similar storage to "Pro": 2.5in SATA HDDs at 120GB & up, 'Combo' or 'Super' optical drive.
• ATi Radeon Mobility X1600 or nVIDIA GeForce GO 7600 graphics systems with 256MB of VRAM.
• Mini-DVI display connector with full second display capabilities
• Of course, Built-in iSight, stereo microphone, Airport Extreme and Bluetooth 2.0+EDR.
• Battery life is expected to be "best in class" at about 6.5 hours real-world, some reports have suggested up to 8 hours is possible.

Final speculation has the "Thin", or whatever they're going to call it, shipping within ten weeks, announced in six. What keeps this speculation iffy is the fact that the upcoming MacWorld Expo is so packed with other high-profile items - such as iTV and the iPhone - that were the "Thin" announced there, it could easily get lost in the shuffle. Not that it won't be noticed by a lot of people who'd love to get a MacBook in smaller dimensions.
