My laptop dates from 2000 and weighs about 30 pounds. Time to replace I want to get a new one but know little about all the jargon. Someone recommended Sony, others say HP or Dell. I looked on Newegg.com and it seems that prices vary enormously even within the same brand. There are a lot of different chips listed, and I have no idea what the difference is (AMD, Intel and all the variations) I'd like something with a decent sized screen and a graphics card that can handle video and PowerPoint presentations. I mainly use MS Office. I assume that Windows 7 is the latest version and the thing to get ? I don't have time to review all this technology myself and become expert. Any input appreciated.
