Hi Rowan,
I'm not aware of any performance difference - i would expect it would
only be on bytecode compilation so a cache like APC would remove that.
Curly makes for easier collapsing of code in your editor and most
editors will show you matching braces so you can match them and see non
matching ones. If you're working on almost any php opensource project
there will be a strong preference/requirement for curly in the coding
standards so I would recommend this in any php code. Colon is nice and
easy to read in templates where it's mixed with html.
From Drupal:
You are strongly encouraged to always use curly braces even in
situations where they are technically optional. Having them
increases readability and decreases the likelihood of logic errors
being introduced when new lines are added.

Which appears to be taken from the PEAR Coding Standards -
http://pear.php.net/manual/en/standards.control.php
Zend refers to the use of braces only -
http://framework.zend.com/manual/en/coding-standard.coding-style.html#coding-standard.coding-style.control-statements
The Horde Application Frameworks says "Do not omit the curly braces
under any circumstance." -
http://www.horde.org/horde/docs/?f=CODING_STANDARDS.html
But if it's just for you then do what works for you :-)
