In related news, Microsoft has also debuted a new variation of the Surface Book 2 with less storage and a lower price. An entry-level model with 128GB of storage and a 13.5-inch screen, 8GB of RAM and an Intel Core i5 processor costs $1,199. For those keeping track at home, that's $300 cheaper than the previous lowest-cost model, but the discount comes at a price: half the internal storage.

Other prices have dropped as well. A Surface Laptop with an i5 processor, 8GB of RAM and 256GB of storage is $200 cheaper now, in what seems like a temporary sale rather than a permanent price cut.

The pair of these "new" devices likely aren't going to make any waves with power users, but they represent Microsoft's next steps for the Surface line. Specifically, hitting mass adoption. The lower-priced Surface Laptop is perfect for people who just need a computer for email and word processing tasks, while the Surface Book 2 could sway potential MacBook Air and MacBook customers toward Windows.

The company recently posted 2 percent growth in its "Personal Computing" segment, and more moves like this could help drive sales and increase that relatively stagnant number.
