I heard some bad things about the touchscreen being really crap, did they fix that at all?
Not really, no. There's a reason why they're still knocking out the 820s at significant discounts so long after the 830 was released. The prices are tempting, but in my book it's a temptation still worth resisting.
If it's just going to be used for training intervals and following breadcrumb grx routes, it might be worth taking a look at the 530. No touchscreen (a good thing), very reliable, same form factor as the 830.
