I have a hard time with small screens (farsightedness) so I only use mobile Internet in emergency cases. Is it a hardware (screen size) problem or a software (too much screen real state eaten by ads) one? I honestly don't know the answer, but it's still a problem.

Edit: I use glasses, specially for reading, but the optmestrists refuse to raise the graduation that would give me a clear vision for small letters. They say it would make the problem worse long term.
