Not sure if it just me but when using google chrome on iPad I cannot seem to up or down vote posts, the arrows seem to just be a graphic and non functional.

Any ideas why this would be?

Not just you, just checked it and same here.

Was waiting to see if Dani etc responded but seems not :(

Sorry, I've been super busy the past few days. Not all of the AJAX functionality on the site is available on the iPad. This is known and, more or less, an "acceptable loss".

Thats fair enough Dani, thankyou for replying and confirming.

Update: Voting functionality is available through the API, so this feature can be implemented should you so desire :) An iOS app is actually in the works and will have this functionality.
