I need a new home computer (using a laptop currently, that's so old it's slowing down). I only use the computer once or twice a week - keeping track of finances, and some small correspondence. Don't want to hang about for the PC to "warm up" (the laptop takes forever!), so I want a machine that comes on very shortly after I press "on", and with a reasonable quality, but nothing fancy. What should I go for? (I'm not knowledgeable about the computer market).
