With the Surface Pro 4, Microsoft's surprising hybrid tablet journey finally makes sense. It's as if Microsoft was laser-focused on fixing the issues we had with the Surface Pro 3. We liked that device quite a bit, but its Type Cover was endlessly frustrating, with a sloppy keyboard and wonky trackpad. The new keyboard, on the other hand, is far sturdier and more laptop-like, and its trackpad is no longer a thing of nightmares. It's taken a while, but the Surface Pro 4 shows Microsoft has finally accomplished everything it set out to do when it unveiled its crazy hybrid tablet concept three years ago (which makes the announcement of the Surface Book even more curious). Aside from improving the battery life and bundling in the Type Cover (just do it, already), it's hard to imagine how much better the Surface Pro line can get.
