But, as it would turn out, I'm not one of those people who is comfortable using a laptop on my lap. . . Hence the laptop table round up -
2. Tucker Camo from CB2, on sale for $100
3. C Table from Crate & Barrel, $59.95
The Crate & Barrel option looks like my best bet, not only is it the cheapest, but it is the only one that would let you use it from the side of the chair.
