I wanted to try the new 8" LCD from Lilliput. The reason for this is that the 8" model is 4:3, not a widescreen. This makes the application look much better and I think the maps are looking better too. The touchscreen is better and more reliable than the 7" model.
The bigger LCD is of better quality, I think. There is only one problem - it is really big. The screen itself is higher (of course) and as much as twice ticker than the 7" widescreen LCD. I have to think of another way to attach this LCD to my dashboard, because it is too heavy for my current cell phone holder.
