While shopping around for some laptop tables, I came across LaptopTableBed.com where I was able to to find just about every kind of table bed that there is to offer on the market.
Some are light weight, fold-able types that would be great for storage or travel. Others are more of a platform, but the problem is they don't let any air underneath the notebook book.
Most of these look pretty stable for keeping the laptop from moving around while typing plus they supply some air flow underneath to prevent overheating.
Some even come with a built in fan and some others could be used for table use, when sitting at the desk or living room table.
The site also has some really cool stands for the iPad I want one even though I don't have an iPad ...Yet !!!
