Should I buy an i-pad? Or is there any Better technology?

I have a smartphone and anipod latest version of apple.

but i'm thinking of buying something with a bigger screen and very easy to carry around like take it to my classroom and somewhere i go…

So should i just buy an iphone? But isn't it a waste coz i heard that samsung galaxy or whatever is cheaper and better? I don't know what's your experience or opinion on this? I think many people but iphone out of peer pressure which is pretty stupid.

Or should i buy an I-pad? Ipad is better i think coz you don't have to pay every month lol or should i just buy a small apple laptop where i can even do my homework? (Type, print)

i already have two laptops btw, both Big.

So yah Enlighten me from your technology knowledge and experience and some personal advice?

Thank you:3

Added (1). Wow i don't know who to choose as the BA:@ lol

My mom owns the Iphone4s and I own the Samsung Galaxy s4. Between using the two I noticed that yes the iphone is a very simple phone and works great… But it lacks with hardware, the CPU in it is not nearly as good as the s4 and apple does dumb stuff like hiding system files so you HAVE to use itunes to add music and such.

I'm not sure what your question actually is lol, since you have so many devices listed… But here is my ultimate advice, if you're going with a tablet get the ipad, if youre going with a smartphone get the s4, if your getting a small laptop get a macbook air.

If you already have 2 laptops, just use them. I think ipad is enough if you just wanna surfing internet or emails, and i think there's not only ipad, all the tablets are only for surfing internet or email(mostly), and ipad or other tablets can much help your homework, except you just wanna to know about something or learning new thing, you can browse it and tablet make is simple, easy and not hard to use, and for Homework just use ure laptop, don't buy a macbook if youre have laptops, because actually they're same, exempt you will goint to design graphic school or like designing school, i recommended using mac because mac graphic is special for this stuff. But if you like gaming like MMORPG or something like that, you must use windows PC, because mac doesn't support gaming stuff(just browser game using flash player), and windows pc/laptop is enough, and for iPhone/galaxy, it's depend on you, every phone most functions are texting and phone, so another things are addition. ( make sure if you wanna buying a tablets, your works on tablet can't be transfer to your laptops, especially apple product). Sorry for my english, hopefully this can help you.

Either get an iPhone 5S(which features a quad core processor, all iPads are still dual cores) or a Microsoft Surface RT(also using a quad core processor). The Surface have free Office 2013 and only costs around 300+$ for the base unit btw.
If you like a macbook, the smallest air is more than sufficient. Alternatively you can look into the surface Pro.
