Lenovo has quietly released a “base model” version of their svelte IdeaPad Y650 multimedia laptop.

When we reviewed the IdeaPad Y650 almost 2 months ago, it came across as a rather impressive 16-inch multimedia machine with a very thin & light chassis for its size. It was also one of the more expensive IdeaPads, generally priced above $1000, although still a value at those prices. Today we noticed that Lenovo has added a new version of the Y650, noted as a “base model.” If you go by specs alone, it is an extreme bargain: a faster processor, 64-bit OS, and bumped up to 4GB RAM for only $899? All it loses from the next model up, which runs $250 more, is Bluetooth. Wow.

Of course you don’t get something for nothing, and judging from the picture above, at the very least the base model loses some of the nifty exterior design work that gives the regular Y650′s their slick design and appeal. While losing only the detailed design work is absolutely worth $250, there are probably other concessions as well.

I am trying to confirm this with our contacts, but my biggest fear is that the amazing Carbon Fiber Reinforced Plastic (CFRP)/magnesium-aluminum alloy chassis has been swapped for something else. While the features and performance of the Y650 would still be a bargain without it, that chassis is what makes the Y650 the flagship IdeaPad and a premium product in the marketplace.
