Samsung unveiled the powerful Galaxy Book at the Mobile World Congress and people are already comparing it to the iPad Pro and Surface Pro 4. But can it really compete? - From Tech Times
Dimension-wise, the Surface Pro 4 is a little larger than the Galaxy Book, though not by much, but it is thicker at 8.5 millimeters (0.33 inches) while the Galaxy Book is only 7.4 millimeters (0.29 inches) thick.
In terms of memory and storage, the Surface Pro 4 offers a 16 GB RAM version, as well as models with 512 GB and 1 TB internal storage.
Microsoft's current price for the Surface Pro 4 (with pen) ranges from $799 to $1,499 while Samsung has yet to release any information on pricing and availability for its Galaxy Book.
The Galaxy Book has an edge over the iPad Pro in terms of expandable storage since the iPad Pro has no microSD slot.
Like the Surface Pro 4, the iPad Pro is already out in the market with a tablet-only price starting at $799, but if you want to level the playing field and buy the accessories, that's an additional $169 for the Smart keyboard and $99 for the Apple Pencil, leading us to a grand total of $1,067.
