As time approaches for me to go to college, I have started thinking about what technology I will need at university, and thus, this could be a great graduation present. I have decided that from today's technology, there are three main types of devices that are dominating the entire market: laptops, tablets and smartphones. In my case, I have always been an Apple fan and bought most of my products from them, thus I am going to create a comparison between their three most famous products (MacBook, iPad and iPhone) in order to decided which one will be more useful for university.

	Macbook	iPad	iPhone
Power	In terms of power, a laptop will always be more powerful than a table or phone. With more storage space, more ram memory and speed, a laptop is useful if you have to program of use powerful applications for design for example.	iPads have gotten to be more powerful over the last few year. Their storage space is not bad, up to 64 gb, but may not be enough for certain activities such as film editing. However, they are more powerful than iPhones.	Similar in power to an iPad, its storage space can be exactly the same as that of the tablet, but the difference is that an iPad can handle more programs and more powerful programs than an iPhone can.
Portability	If size matters, then a Macbook will always lose. It is much heavier and bigger than an iPad or iPhone, so if power is not an issue for you, then I would not recommend a laptop.	iPad is the second on this list in terms of portability. Even if it has gotten lighter and lighter, it cannot compete against the 114 grams of the iPhone. However, its weight compared to its huge screen is very tentative, with the option that there is an iPad mini, which is smaller and can be carried practically anywhere.	The iPhone is by all means the most portable of the 3. Its 114 grams and 4 inch screen can be carried without you noticing in your pocket. For that reason, if the size of the screen does not matter, an iPhone is perfect for you.
Battery	In terms of battery, it would be the second in my list. With up to 9 hours of battery life, or that is what Apple says, it can be used throughout a whole day without having to charge it, and use it even more if wifi is not required for the task.	The recent models of iPad are estimated to last around 10 hours, but my personal experience confirms that the battery can last way more than 10 hours, and that gives a plus to the iPad in this aspect.	By far, iPhone has the least battery life. It is said to last 8 hours. However, the 3G or 4G network makes the battery last for approximately 4 hours if used constantly, thus having to charge the phone every day, something that is not good.
Multi-tasking	By far, a laptop is the best device of the three to multitask. You can have as many open application as your RAM permits, which makes it very easy to change from one application to another.	Multitasking in the iPad and iPhone is exactly the same, so I am going to join both in this aspect. Multitasking has become better in this devices, however one has to leave the application to then go on to the next one, which can get to be really slow if working with many open applications at the same time.	Same as the second column for iPad.
Other features	Some other features I am going to include are the camera and the data connection. Laptops to start with have only the frontal camera, which by all means is not comparable in quality with iPads or iPhones. Second, it cannot have data connection, and by this I mean 3G or 4G, thus you depend on a wifi network if you want to surf the web.	The iPad has a wonderful camera,  although I have to say that at the beginning it was quite poor. It has now a camera of 8 megapixels that takes fascinating photos as well as HD videos. In addition, it has the option of adding a Sim card, thus having the possibility of having a data plan and internet everywhere you go.	The iPhone has without doubt the best camera of the 3, with incredible resolution photos as well as HD videos that can be seen crystal clear. As it is obvious, it has 3G and 4G, and even in the USA LTE, which is said to go way faster than any wifi connection, thus having a huge advantage over the laptop in this aspect.
Price	All of these devices, being from Apple, are quite expensive, but some more than the others. For example, a Mac laptop, starts at $999 for the Macbook Air and $1299 for the Macbook Pro.	The price for the new iPad air starts at $499 for the 16 GB model, and in the case of the iPad mini, from $399 its 16 GB model.	The new iPhone 5s has a starting price of $649 unlocked for its 16 GB model, but of course the telephone companies make different offers in which the phone itself may be less expensive.

Although this list gives you a basic idea of what the features of each device are, it is a combination of different factors that will make you decide one from the other. In my case, I am going to study engineering, therefore I am going to do a lot of programming and managing a lot of different powerful application. For that reason, I would probably buy a powerful laptop in order to program (something that you cannot do in table of phones or at least that I know of) and manage all the programs I am going to need with the laptops' excellent multitasking feature, something that tablets and phones still lack. For this reason, a laptop is my choice, plus the fact that its battery is getting better and better and may last a long time without a wifi connection (which is not always necessary) and its large screen, which for programming is once again vital in order to see the characters clearly.
