Pros Keeps hot laptop off of lap. Storage is useful for small items (extra usb cable when not in use, smaller ac adapter).
Cons notebook "sinks" into foam cutting off air circulation (contrary to other review)
Summary The small rubber nubs on bottom of computer compress the foam allowing the entire bottom of the laptop to have contact. I realized this after noticing my fan running at a very high speed. but I wasn't doing anything that put a heavy load on the processor (just surfin'). When I leave my laptop on it for any length of time with the top closed but powered on, the touch pad is quite hot and the fan sounds like a jet engine.
This product could potentially be harmful to your notebook if used for long periods
Pros Good lap desk, fits AC adapter.
Cons Non-tiny mice don't fit. There should also be a mouse area.
Summary It's good for putting a laptop on, and my AC adapter also fits well inside for carting the whole thing around the house. The big side is just big enough for my 17.3" laptop.
However, my mouse doesn't fit in the hole. Also, there is no way to hold a mouse in a comfortable position (ie, right next to the keyboard at the same elevation). It seems like a no-brainer to develop a mousepad insert for that giant hole on the side. Overall, it's good if you have a good touchpad and don't need a mouse to comfortably use your computer.
Pros effective insulator; firm top
Cons too large; makes keyboard too high; bottom too hard (because it is a "second top")
Summary The CushTop is a well-made item. However, it is unnecessarily large--both width and height. As a result, my dog can't lie beside me and, more importantly, the keyboard is at too high a level unless you sit with your thighs slanting downward (which I don't in my La-Z-Boy). The storage space is essentially useless: I'd have to force my Dell recharger into it and it's not wide enough to hold 8-1/2 x 11 papers. The hard top is a good idea; I can use it to do Sudoku or crossword puzzles. But because the item is (unnecessarily)reversible for different width computers, the part that touches your thighs is too hard. In fact, calling it a "cushion" is misleading; it is just a firm insulator. Overall, I like using a folded up bath towel better.
Pros Comfortable to use - not too bulky or heavy - can store powerpack
Cons Not as cushy as some "pillow"-type lapdesks
Summary Contrary to what Cnet indicates in its review, this product can be utilized with a 17in laptop - just turn it over from the configuration shown in the picture. The slot in the middle of the CushTop is quite narrow - a mouse won't fit, but a laptop powerpack just makes it, along with the cord - so it's convenient in that sense.
It's a no nonsense lap desk and could even be used to write on, as the "padding" material, if it can be called that, is quite stiff. because it's so stiff, there is ample ventilation for the bottom of laptop. On the downside, it's not quite as comfortable as some lapdesks with cushions. However, I don't think it will even lose it's shape (unlike those cushions lapdesks).
