Are Kindle Fire and toublet better than Iphone?

If the user is going to use it not for phone.
Iphone is very good, it can put in the pocket. They can always be with me. Tablets need a bag. But display is too small even it is Iphone 5.It is too small to use it for websites, even photos, videos. Iphone 4 are cheap but, with price of Iphone 5 I can buy tablets. There are smart phones that has large display, but they have low battery life.
If the Tablets price are same or cheaper, it would be better to buy Tablets?

bad thing about tablets is it's large that people will see it easily, won't have a privacy.

What is a "toublet "?

  • Should I sell my kindle fire? I recently won a kindle fire hd 7". I'm not sure whether I should keep it or sell it and use the money for a laptop which I will need for college. I already have an iPhone and iPod touch so I just don't know what to do
  • Should i get the 7 kindle fire HD or the Kindle Paperwhite? I already have a Macbook and iPhone, thats why this decision seems hard for me. Also, can someone tell me more about Amazon Prime? If i get a Kindle should i get it? Is it worth it?
  • Should I buy a Kindle Fire if I have a Iphone? I'm considering buying a Kindle Fire but I have a Iphone will the Kindle Fire be any use for me?
  • My Netgear Wi-Fi won't work on my iphone or kindle fire? My Wi-Fi was working perfectly fine but then just stopped working. Now my iphine and kindle fire can't find our Wi-Fi. Even my laptop says no networks found. I'm still able to get online through our home computer which is ran by hughes net but thats it. On the netgear modem the lights for power, internet and number two are all on so i have no idea what's wrong.
