Hello, I'm thinking about possibly purchasing an iPad this year, when do new iPads get announced usually? is it worth getting one now/in a month or two or waiting for the next gen iPad Air? I'm mostly going to just be using the iPad for web browsing around the house, checking e-mails, etc. and want an iPad that'll last awhile before needing to upgrade again. 
Thank you
