Different form fields: mobile v. computer browsers?

We are creating a page which includes an input field asking for a
user's e-mail address paired with a second field asking them to
retype it to confirm.

This page will also be offered for users visiting with a mobile
browser and we have been debating whether to drop the confirmation
field for mobile users since it would seem to be more of a nuisance
in that context.

Is the assumption that we should drop these "luxury" fields for
users with mobile browsers a good one? On the one hand, it saves them
time and effort. On the other hand, it may allow for increased user
error when submitting e-mail addresses.

Related to this, does anyone know of any good resources (free or
paid) that collects best practices for IxD for mobile browsing?

Hi Eric

Is there a particular reason why you need to double check that the user has
entered their email address correctly? I'm sure you're aware that when
registering on most well known sites, the user is not required to type their
email address twice - this is reserved only for passwords.

I'd remove the "email confirmation" field unless you have a really solid
reason for needing it...

I hate the double entry and haven't understood its utility. Does it really drop rates of erroneous entry?

I use the browser auto-suggestion when I can. Or I copy and paste from the first entry, thus preserving any error.

Net: I think drop it. Mobile is a different context (many of them) anyway and people need less clutter.

Absolutely drop all but necessary fields for text entry for the mobile

The amount of people giving up with just one entry field is enormous,
let alone two. Remember that mobile users are situated in other
contexts where they will get distracted by the rest of life. :)

A few questions to ask yourself...

What does your site offer that requires signing in? Does that use
case still exist in a mobile context?

Can you simplify the service or offering?

What is the profile of the person using the site?

Text entry is okay on iPhones and Blackberries, but they represent a
relatively small amount of users in the global market.

Thank you for your responses and for the link to the mobile UI pattern
library. You have confirmed our decision with good reasoning.
