I am very tempted to buy a Google Nexus 10. I am a bit concerned that the Google Nexus 10 only uses a 5 volt charging port. There are other Retina Android retina display tablets available. But the there resolution is still using 2048x1536 retina display resolution. So I am wondering if anyone has heard if there will be tablets that will have the same resolution as the Nexus 10 soon....?
