Вставить артикли though you can make decision on purely economic grounds, buying computer is often more like joining religious cult. buy apple, for example, and almost by default you join apple chairman steve jobs in his crusade against ibm. every machine has its "users' groups" and band of loyal enthusiasts who tout its merits. that makes it all more difficult for uninitiated to decide what machine to buy. students have huge advantage, however. the computer companies are so eager for students' business (it builds "brand loyalty") that many offer huge discounts. in the past six months, ibm, apple, and others have brought out new computers, and fierce competition has forced prices down. also, time is on your side: next year at time you'll have even more choice and more computing power and features for same price. on other hand, this will probably be true for many years. so for those who need or want computer now, it's a great time to buy one.
