What device/software best for trading away, for quick looks

i’ve got a mobile phone with a larger screen but the screen is still too small i think. what is a good device to use when people are trading away from home and need to take a quick look at the charts? ideally the device turns on quickly and is good enough visually to see charts well enough and make decisions. any suggestions?

I use a Samsung 10" tablet, works for me

i just thought i’d add a helpful tip i use now:

when turning off pc, put computer into hibernate mode. it will turn on really fast.
(and thx for the samsung 10" tablet idea)
