Faster laptop helps..I use an i5 with a SSD and it’s perfectly acceptable…
Horse for courses…Foxwell very limited functionality but probably does most things for most folks…
ISTA much more capable but probably too much like hard work for most…
I have a Foxwell and ISTA but use Bimmergeeks Protool on E89s..doesn’t work on E85s..
Far more capable than Foxwell but almost as simple to use..
