Is Raspberry Pi Good? (Computer/Tech Guy Recommended)?

So my friend told me Raspberry Pi is EPIC. It has 700mhz, which is less than my computer and iphone 4s. I'm wondering. Is iphone and windows phone better than raspberry pi mini laptop?

Better at what? The iphone 4 will be faster at some raw calculations, and will certainly be a better phone.

The pi will easily interface with lights, sensors, breadboards, and can pretty easily do 1080p output to HDMI. It can make a cheap media center.

If you're not wanting to make something with it, then it's probably not as useful as an old laptop.

  • This cable is not recommended for this iPhone and may not be reliable? I recently bought a new but un-Apple-certified lightning cord for my iPhone 5c, but this error message has started popping up after about using it about 5 times. Now, my phone is completely dead, and I have no money to buy a new cable, no cable that will charge my phone, and a dead phone. I'm completely desperate for help here, since, like a cliche white girl, my phone is my life.
  • Recommended Kanji Dictionary iPhone app? I'm looking for an iPhone app that is a Kanji dictionary where I can write an unknown kanji and it will give me the meaning. I would prefer it if it works even if the stroke order is wrong because I'm not always sure about how to write it. I just need it solely as a dictionary. Teaching/quizzing me isn't necessary Free is the preferred option but I will buy it if it's good.
  • Recommended case for iPhone 5c? I've always been clumsy with my phones (my last one had a big crack in the front AND back…) and I just recently got an iPhone 5c. Considering the outside is made of plastic, I'm going to need a sturdy, protective case. I'd like for it not to be very bulky so it can slip easily in my pocket. Any recommendations?
