Title says it all. I'm a new smartphone user (the Galaxy Centura is enroute as I type) - and trying to make decisions about accessories - particularly the SDHC card. As I understand, max size is 32GB -- which I'm leaning towards. Don't plan on using the device as much more than a phone, but would like to have the ability to load up with useful apps. Is there any downside to a 32GB card? Speed? Battery life? Help respectfully requested. Also - for all you 'old-timers' out there, any other neat and/or useful accessories for the Centura? Thanks in advance. -- john.
