It depends largly on the person using the laptop. It also depends on what the laptop is functioning like. If it is used for business and is used nearly daily I would recommend having a fairly nice one that has nice RAM, good Operating System, nicely functioning software, connection, etc. So if I was recommending a buy of a new laptop, either for regular or business use it would be either a Compaq, HP (Compaq is owned by HP, so there are only about 2 laptops on the site,) Dell, or a Sony Vaio. But considering your question, generally, if it is a home computer used maybe 4 times a week you probably want to get a new one in about 3 years. For business you should have a nice laptop anyway so, generally, I would say that probably every 3 years as well. You may need to upgrade earlier, though, so, in which case, I would say that you should get one with at minimum the following: 1 GB RAM Windows XP DVD/CD Rewritable Disc Drive (Optional) 3+ USB Drives 802.11g Wireless (Virtually any built in wireless card) Pentium 4 (Intel) 17+ inch screen Output to a monitor Etc.
