Besides looking at the speed of the processor, and the look-and-feel, what else should you be looking for in a notebook?
Computer manufacturers typically group their products by market segments, either targeting consumers or commercial. Computers sold to consumers typically comes with 1-year warranty, whereas those targeting businesses tend to have 3-years warranty. Repairs to computers, especially notebook, can be expensive. So having a longer warranty makes a lot of sense.
Warranties can be either carry-in to service centre, or on-site. If you are running a business that cannot afford to have a person waiting at a service centre for half a day, then give this a serious thought.
You don't want to be buying a slim and sleek notebook only to carry a power adapter everywhere you go. Nowadays, batteries on some ultrabooks can last in excess of 10 hours. This usually comes at a price premium. Consider getting a notebook that balance weight versus battery life.
Having a high resolution screen is nice, but at the expense of battery life. If you are just using the notebook for general office use, consider getting one with lower resolution.
So also getting a notebook with an i7 processor will have a shorter battery life compared to one with just i5. You may not realize you don't really need that much processing power after all.
SSD stands for Solid State Drive. Instead of storing your data on spinning platters, SSD stores data on memory chips.
An important factor to consider when choosing a notebook is robustness. If you tend to use your notebook while moving around, then a notebook with a traditional harddisk may crash easily. Remember that in a harddisk, there is a very delicate reading arm that flies at a hair's breath above a spinning platter. A slight movement can send that arm crashing on the surface of the platter.
Because there is no moving part in an SSD, performance of SSD is also a whole lot better than a harddisk.
