I'm running Opencpn on a Fujitsu Stylistic ST4121 with XP for tablets and a daylight viewable touch screen. The cpu is 900mhz and it has 750 mb memory. I have a waterproof keyboard for typing. I ran Opencpn 2.3 on my trip from Batlimore to Guatemala
. I'm currently running 2.5 at home. The st4121 is a little slow for planning routes, where there is a lot of quilting. I built a plastic case to keep spray off and kept it in the cockpit
except for offshore
I only spent $150 three yrs ago for the st4121. I just checked ebay where I found that they don't even sell them anymore, but there is something similar offered by Motion Computing. When the St4121 dies I'll probably get one of these.
It may be due to my old eyes, but I find a normal laptop
screen to be unreadable in the cockpit
. This is true even when the sun is bright but not directly on the screen. Perhaps with some sort of hood
