At MWC in February, Samsung also announced the Galaxy Book Windows 10 2-in-1 alongside the Android-powered Galaxy Tab S3. The Galaxy Book is basically Samsung's answer to Microsoft's Surface Pro line.

Today, following quite a wait, the Korean company is finally ready to share details about the Book's availability and pricing.

The 2-in-1 device will be out in two sizes: 10.6" and 12". The former will only be offered with Wi-Fi connectivity, priced at $629.99. Pre-orders start on April 21 at Samsung's online store as well as select retailers such as Best Buy. It will be released on May 21.

The Wi-Fi-only version of the 12-inch Galaxy Book is priced at $1,129.99. This will also go up for pre-order in a couple of days and has the same May 21 release date as its smaller sibling.

If you want LTE connectivity built into your Galaxy Book, only a variant of the 12-inch model will give you that. This SKU becomes available at Verizon on April 21 for $1,299.99.

The huge pricing gap between the 10.6-inch Galaxy Book and the 12-inch versions is explained by the differing specs. The smaller device is lower-end, sporting an Intel Core m3 processor, 4GB of RAM, and a 30.4Wh battery. It's also got a plain TFT touchscreen, whereas the 12-inch Book features a higher-res Super AMOLED panel, Core i5 processor, and up to 8GB of RAM and 256GB of storage along with a 39.04Wh battery.
