It looks like it's about 3-4x more on ebooks for me. I voted for 5x.
I've been tracking my ebook expenditure with a spreadsheet for a while now, but I know it's missing at least one storybundle, and I haven't counted Hugo voter packets or any proportion of my Prime subscription. The spreadsheet total is a little over £1000, since the beginning of time*, which is quite handy for the simplicity of the maths.
I have three e-readers, which cost a total of roughly £235. I haven't spent a lot on covers, let's say £15 per device, giving me about £280. My old Kindle is crying out for replacement, though. The battery barely last a whole book any more.
*2010, when I got my Kindle. I didn't pay for any ebooks before that, just picked up a few freebies, mostly from Baen.
