1.The performance "Can i run GTA IV or oracle database on a netbook?" Buddy, you need a ture laptop such as Dell XPS laptops, instead of a low-power netbook. In performance terms mini laptops trail behind mainstream laptops. But don't underestimate the capabilities of them, they are not toys. Netbooks can be used for web surfing, word processing, spreadsheet work, photo editing task, video chat, watching youtube online, update your twitter/facebook page...etc. You can run your iTunes, office software, email client, personal finance software and light games on them, even World of Warcraft if you buy an asus EeePC N10J. All netbooks can do these well, but do not ask too much of them.
2.The size Most manufacturers offer netbooks with an 8.9 to 10.2-inch wide screen, a 3-cell batteries(3hrs) and a near-fullsize keyboard(92% of a full-sized one) as the standard. So be sure you take a good look at this, as it can negatively impact fast typists. The merits are mini and portable, easy carry from room to room.
3.The os/software There are two operating systems need to choose before shopping, windows XP and linux. Generally speaking, linux is fine, but most people are used to working on windows os. And if you want to install any windows software, such as iTunes, aol/bellsouth broadband dialup software, windows XP should be your choice of OS.
4.The price Generally cost between $300 and $500. The most basic model can be found for around $350. These basic models are powerful for performing basic tasks, and for some people they may be the best laptops money can buy.
5.The style Style design is more important for anyone who is interested in fashion. Please focus your minds on these models if you want more: Asus EeePC S101, HP Mini 1000 Vivienne Tam and Sony VAIO P netbook.
Simple, cheap and mini. That's mini laptops. Provided you do not expect too much, mini laptops will be the best choice.
