Mobile can now be versatile, someone who doesn't have a computer can still do airdrops even in a browser can be desktop mode.
I run airdrops on both mobile and PC for me both are very useful especially computers which have a wide view while mobile is limited.
Regardless we can do airdrop on mobile.
I've been tparticipating in various projects for some time now
Sometimes I've had to travel and I didn't have a laptop with me, so I had to use my smartphone, and the experience is still very difficult and time-consuming, especially when it comes to using a wallet, making certain transactions, some operations on DeFi sites...
There's still a long way to go for platforms to be optimized for mobile
if you don't have a PC or laptop, you can use mobile, but it takes a lot longer and requires a bit more patience
