If you are interested in buying a Nexus 10, now is as good a time as ever. The Nexus 10 is back in stock on the Play Store for US customers, and is stated to ship in less than one week. You can get both 16GB and 32GB versions now, for $399 and $499 respectively, so you should jump on this before the shipping date is pushed back or they disappear entirely. Really, act quick!
Samsung Galaxy S3 (GT-I9300) has an update to 4.1.2 I believe as I'm getting an "Access to the software update service is provided to users in the order in which they request it. Try later"; I'm upgrading it through Kies.
Just a heads up.
