daniel, ill share my philosophy on laptop mounts and vehicle mounts in general...there are a couple elements i always consider before making any kind of installation inside of a vehicle...one of the first things i look at is the simplicity of the device, because theres nothing i hate more then sitting down and trying to build some wild mount thats going to consume time, money and effort...
there are several mounts out there...some are proprietary to the vehicle their designed for, while others are universal meaning you can put em in any car and they will work...alot of mounts can be expensive though, and some mounts take the vehicle away from the vehicle and become an eyesore after a while...some people like that look, so i guess its what all your into...also, not sure if others can tell you but i would be concerned about having security issues with a large mount in the car...people would know that you probably have expensive stuff in there, and if they know your vehicle enough they might try to get in there and jack your stuff...
i will tell you that i am a strong advocate of velcro...my whole set-up is based on velcro, and im very happy with the results...the thing about velcro is, its cheap and its plentiful and it is flexible...you can use it for anything, including mounting a phone or ipod and if you want it gone...all you gotta do it pull it up...you can put velcro anywhere you want, and in the case of my vehicle here...my dash comes out at a 90' angle which lets the laptop ride easy without any risk of it falling, the velcro keeps it securly attached and when i get to where i got to be, all i gotta do it pull it up from the pad and shut the dash and its like it was never even there...
every thing you see in this picture has been installed using velcro...needless to say its not for everyone, not all vehicles will have this kind of configuration and thus wont let you do the same thing...if you ever needed to buy a commercial mount, i would reccomend a ram-mount...they are pretty good in terms of costs and simplicity of design, and also dominate the market...if your talking about mounting a camera, i strongly reccomend the sticky-pods...they are similar to the velcro in the fact that they are universal and can be taken out of any vehicle and put in another one...they are cheap and simple to use, but very effective...
anyway, just a couple of things you might wanna consider...
