Google Maps API V3

I was doing some work with  Google Maps API V3 during last couple of weeks,
and here are some of my experience with this version.

• Very small footprint and quite fast.
• Although in Beta I think it is quite stable to be used in production - if of course you are ready to follow with latest developments and fixings.
• A small but annoying bug I discovered (for which I filled a ticket : http://code.google.com/p/gmaps-api-issues/issues/detail?id=1643 along with a work around)
• A tip : Since there is no way to hide-show the zoom - pan and Map type selection controls through api you have do it by writing some javascript 

        var housediv=yourmapObject.getDiv();
        if (housediv.childNodes[3]) { 
            housediv.childNodes[3].className = myClass 
            housediv.childNodes[4].className = myClass 
        } 
         // if exist 
        //controls reside in childnode[3] and [4] of container div 
        //rest is done with CSS class where you can hide-show or change the opacity
