I have been thinking that my next phone will be 7 inch tablet. No, not the neutered nexus that has no sd card and no hdmi.
I can see going to any cell company and buying a USB stick.
voice can be via VoIP, either Skype or Google voice.
The tablet can fit in a jacket pocket, and a Bluetooth in my ear for phone use.
It will have a nice larger screen for web browsing, all my familiar apps, large sd card and hdmi for watching movies and tv shows on a HDTV.
It will be global, as all that is needed is a 4G USB stick and month by month prepaid plan. if New cell technology arrives, then buy a new stick. Want to change cell company, then buy a different stick. New android os is released, then download it from the tablet manufacturer website. Want a aosp Rom, then download it from the internet.
I have a dream...of no Verizon bloat, no waiting for Verizon to bless an OTA update, no long term commitment to any cell company, etc etc
Unfortunately, I still have a year left with Verizon.
