For using Access you have to get a machine running full Win 8 & Office. There's no sign of a port of Access to WinRT. Only way is to use remote apps, some user have reported this as a convenient solution.
Isn't Access going away? I thought that they tried to completely get rid of it in Office 2010 but customer demand had them finally include it. I wouldn't be surprised if Office 2013 doesn't have it at all. I still use it for some old legacy DB's I use but that's only because I've been too lazy to port them to SQL. They're really not that important to me.
