This is what I use to handle magic quotes

<?php

if (get_magic_quotes_gpc()) {
    function strip_array($var) {
        return is_array($var)? array_map("strip_array", $var):stripslashes($var);
    }

    $_POST = strip_array($_POST);
    $_SESSION = strip_array($_SESSION);
    $_GET = strip_array($_GET);
}

?>

Another reason against it: security. You could be lulled in a feeling of false security if you have magic_quotes=On on a test server and Off on production server.
And another: readability of the code. If you want to be portable you need to resort to some weird solution, outlines on these pages (if (get_magic_quotes())...).
Let's hope magic_quotes soon goes to history together with safe_mode and similar "kind-of-security" (but in reality just a nuisance) inventions.

I find it useful to define a simple utility function for magic quotes so the application functions as expected regardless of whether magic_quotes_gpc is on:
function strip_magic_slashes($str)
{
return get_magic_quotes_gpc() ? stripslashes($str) : $str;
}
Which can be annoying to add the first time you reference every $_GET /$_POST/$_COOKIE variable, but it prevents you from demanding your users to change their configurations.

Additionally, addslashes() is not a cure-all against SQL injection attacks. You should use your database's dedicated escape function (such as mysql_escape_string) or better yet, use parameterised queries through mysqli->prepare().

It is also important to disable Magic Quotes while in development enivronment. For the reasons mentioned above, not everybody is using Magic Quotes.
An application that works fine with Magic Quotes enabled may have security problems (ie can be subject to SQL attacks) when distributed.
