Once you make the move to putting a laptop on your desk for full-time use, a new set of issues and concerns pop up, as any laptop used long enough is going to present ergonomic challenges, particularly because of the flat keyboard designs and placement of the display.
If you don't use a docking station with a separate keyboard and monitor, the next best solution is to use a laptop riser--a stand that both elevates the display and puts the keyboard at a more comfortable angle.
Logitech's $29 Notebook Riser N110 doesn't break much new ground in this area, but it offers a decent amount of flexibility and folds down flat for easy storage or transport when not in use. The off-white plastic base has green accents and gently rounded edges, for a clean, if generic, look.
A small latch allows the bottom panel to slide away from the base, forming an angle at one of three different settings, 20, 30, or 40 degrees, and locking into place. The main plate is 14.1 inches by 10.1 inches, but enough for most 15-inch laptops. Set to the highest angle (40 degrees), the rear edge sits 7 inches from the ground, but only 4.1 inches when set to a 20-degree angle.
