Thread: How big is too big?

You can buy touch overlays for 12.1" and there are plenty of 12.1" around because it used to be a common laptop size. But you're smoking crack if you think 10.4" is too small! Most people here think 7" is 'big'. I think 8.4" and 10.4" are nice sizes, but anything bigger just becomes a pain in the but to install and takes up too much space in your dash. There is nothing you should be doing while driving a car that would require a bigger screen.

For back seat you could get a 14" or 15" for pretty cheap, but at that point why even do touchscreen? If you have that much space to have a huge monitor you have space for mouse and keyboard too. But apparently this computer isn't going to be used by the driver or for things like mp3, gps, etc... so why not just have passengers use a laptop?

There are 14"-15" touchscreens on E-Bay all the time!
for about $350.00

10" is too small due to the GPS program. With a 10", I only have a map viewing area of about 3x4". I don't want to have to stare at the map in order to get the info I need. With a large screen, I can simply glance at it. I will also have a keyboard and mouse - can't right click with a touch screen. I wouldn't say I'm smoking crack - it's a matter of proportions - you wouldn't put 31" tires on a Mini, but they look perfect on a truck.

Have you guys ever been to Hong Kong International Airport? They have 42" Plasma wide VGA touch screens all over the place for airport navigation. It tells you where the nearest restroom, food, and shops are. It also gives you directions on how to get to your gate. When I first saw it, my jaw dropped. I was thinking damn that would look good on my dash.

If it's wider or taller than your car, then it's too big. I would get new GPS software.
