In Today's world, it's as though the laptop computer has been outsold by the new "techie" craze--The Tablet.
You still need a PC to conduct business, or if you prefer Mac's over them, OK. But with technology advancing all the time, it's not uncommon to see people on their tablets or "smart" phones--which in an essence are a smaller version of a tablet.
They're pretty cool, the Smart Phones, you can obviously call on them, text, and have conversations at mcdonalds with your friends across town(or across the dining area). There are no additional charges, and you just have to use Google Talk and Talkatone. Both work together to create your Tablet Cell-Phone. It's kind of funny! Watch out Samsung Note II, your bigger brother is(really bigger)than you!
As I remember, you have to first get the google talk, which will get you your phone number, and will allow you to pick your phone number from a list of numbers from your area. Where I live, my little town wasn't big enough for numbers, so I went to the next bigger town. Most likely won't happen to you. Not a big deal, just want to let you know that you won't be able to use your cell phone--at least not to my knowledge.
WI-FI: You'll need that Wifi area to allow you to give you the phone tone. Note: some areas don't allow you to use the talktone/google talk so I just want to let you know now: It doesn't work in ALL areas!
So, there you have it! You have a free phone, within a Wi-Fi network! You could use it as a separate line, or as a fun phone, or, if all of the phones are used up in the house. Use it as a business line.
My experience, I really trust the Samsung phone line. My tablet is the Tab II 7, now they have out the Tab III 7, little difference. I have used cheaper tablets, but most of the ones I have used, without mentioning their names, don't work, or at least don't work well what I have tried doing.
Invest in a better tablet, and don't go cheap on buying the "cheapest" tablet to hope it will work. I don't know all the specifics on why a better made tablet works better than a cheap one. I just don't waste my time on them.
PROS: It's a Free Cell Phone within your network, and you can make phone calls, at least to my knowledge within the continental USA.
CONS: Not all networks will be ultimately compatible. Do some testing around areas. Have another cell phone with you, that you know is reliable. It's not the most private either, it's like having your phone on speaker phone, so it's louder. The phone number on the other end isn't the same as yours. You have to tell people you call that it's coming up as a different caller ID. Can be bad if you want people to know it's you.
Bottom Line: It's worth checking into, the worst case scenario is that you won't be able to get it to work, but if you do, you have yourself a free phone. Like I said before, I didn't test all areas like Starbucks and McDonalds, Arby's, etc.
