The nexus 4 is a phone and 7 and 10 are tablets. I am going to talk about the nexus 4 because this is the device that both amazes and disappoints me.
First of all, here is the information on all 3 devices: http://www.google.com/nexus/
Now onto the nexus 4:
Quad core processor
2 GB Ram
So what disappoints me: NO 4G. I really wish this phone had 4G. And since this phone is HSPA I am not 100% sure it will run on verizon (rumor is that it will not work on verizon) but it will definitely with ATT.
Now why is this phone the best phone on the market right now: I can buy an unlocked version for $299. Thats right, under no contract with a carrier I can buy this phone outright for $299.
Now for those that do not know what this means let me share with you….When you normally get a phone under contract through verizon/att you pay $299 for a phone that normally costs $650. So you actually pay for that difference in your contract, meaning that your plan is higher than what it really should be so that you pay back that difference in the 2 year contract you sign. So technically when you buy a phone outright, your monthly plan should be significantly cheaper. But its not, why? Phone companies are making money off of you not knowing this information. Well the information is well known just not by the general consumer so no one complains. So if we start buying phones off contract then companies will have no choice but to get rid of their ridiculous monthly fees that we are currently paying.
