I think it varies with country. On some country like here in India most 
of them come with 32 bit uefi due to oem agreement I guess.

Hp claims they ship over 13 million units per 3/4-quarter only in US 
and more than 80% are windows. That's how I deducted the number.

As for 32 bit uefi, Many dell inspiron i3 ($300-$500) still have 32 
bit. http://amzn.to/2kjv6Gf

Asus X and R series : http://bit.ly/2fHspJG  (Only windows 10, dos are 
fine)

All the Asus cheap eebook series , like asus x205ta, 
https://www.asus.com/in/Laptops/ASUS_EeeBook_X205TA/

Those which are pre-installed with ms-dos are fine. Also I found some 
are listed in Ubuntu Desktop certified hardware but the are with 32 bit 
uefi.
(Technically it's ok, because on the website, Ubuntu 16.04 is listed as 
supported and 16.04 has 32 bit. )

I have used hack from 
https://askubuntu.com/questions/392719/32-bit-uefi-boot-support and from
https://askubuntu.com/questions/749306/

After installing everything works out of the box including sd-card 
reader which never worked prior to 17.10.

Suggestion:

We only require bootia32.efi on EFI/BOOT/ and i386-efi in boot/grub. 
May these can be shipped with the iso?
That's what debian multiarch iso does 
(http://cdimage.debian.org/debian-cd/current/multi-arch/). This means 
both
grub-efi-ia32 and grub-efi-amd64 needs to be pre-installed for the live 
iso. Thoughts?


Thank You.
