I am also a fan of the Google Nexus devices. You get great products for a small price compared to
other devices with the same specs.
You get no sdcard slot at any of the Nexus devices, here you have to consider if the internal storage is enough
for you or not.
Especially the new 2013 Nexus 7 is very interesting. If the rumors are true we see in October a new Nexus 10 Tablet and a the new Nexus 5 phone loaded with Android 4.4 KitKat.
