Advice: Looking to take the plung into the Android World

I have decided I would like a tablet and Android is know a mature system. The only tablet I have had in the past was a really cheap crappy Android tablet (I think Google should try and stop these because it gives uses the wrong impression of the OS). Apple is definitely not an option for me the apps may be numerous but I hate the OS. I would like a 9-10" device with sdcard slot. What would you guys recommend? or should I wait for Google announcement in a few weeks? For info devices I have at the moment are: Windows 8 Desktop for Photoshop and coding etc Mac Mini under the TV for running XBMC Windows Phone Xbox 360 Kindle eink
