Samsung Galaxy Book review: You're better off with a Surface Pro

t took a few years, but Microsoft's Surface Pro line is an undeniable hit. It also popularized the convertible tablet category: touchscreen-driven devices you can hold in your hands that also have power and attachable keyboards for getting "real work" done. The Surface Pro's success means it has its fair share of imitators, from Apple, Google and the swath of Windows PC makers out there.

Naturally, Samsung produced its own, last year's Galaxy TabPro S. That device features a great screen and solid battery life but was hurt by a terrible keyboard and slow performance. With the new Galaxy Book, Samsung appears to have fixed those issues -- this convertible has a more spacious keyboard and Intel's seventh-generation Core i5 processor on board. But all that power introduces some unfortunate trade-offs.
