I posted this in my dash thread last year, but it applies. Last year was my first year chasing with multiple data resources. I use all three, but phone much less due to small size. Phone is my hotspot. Smaller tab runs maps and web typically as well as radarscope (lightning tracking), larger iPad runs radar and maps, but its a gen 1, so fairly limited in anything else. Previously I chased with iPad and a less capable phone, however I managed. Having three devices really boosted the ability to get quick info on the fly without having to worry about switching, even though switching on an iPad is super easy, just never know when the tablet will decide to restart an app for you.
IPAD mounted on a 22" Arkon seat bolt arm and gPad mounted to a custom bracket mounted to said Arkon. Everything is easily withing reach, although the tablets could be close, but as you can see, need room to be able to shift.
I've added a HAM radio this season (will take operator test when I get time) and always have a battery powered weather radio as well. Also CB, although it's proven mostly useless aside from weather bands and getting a random chuckle when catching "colorful" trucker conversations.
That being said, I have no experience with laptop chasing but I can definitely see the potential benefits.
