I've been wanting to buy a White Macbook for a long time but keep putting it off because I've read about so many defects. I've noticed now that a lot of the news articles and threads I've read online about these defects are around a year old. I've owned Windows based desktops and laptops since forever and have never used a macbook, only an iMac at college and university. Therefore I have never had any first hand experience of using a Macbook daily over a long period of time. The problems I've read about include; Extreme over-heating The exterior cracking in various areas The Macbook adapter and Mag-save cord melting/exploding Screens displaying lines all the way across Hard disks completely failing and having to be replaced. All of these problems are worrying, especially the last one, since you lose everything. The others of course are also very off-putting. So, what I want to know is whether these problems and any similar problems have been acknowledged by apple and fixed for the current version of the Macbook or do some of them, or any other extreme problems still exist? I would be using it every day for a max of 7/8 hours, mainly browsing the net whilst playing music on iTunes, maybe streaming a movie from my hard drive like once a month. But I'd also be using word processing software from time to time and regularly using Photoshop, Illustrater and Dreamweaver for University projects. Like I said I've only ever used an iMac at college and university, never a Macbook and I've only ever heard of Macbook's suffering from these defects. If it help's the Macbook I'm thinking of getting is the middle one listed at http://store.apple.com/uk/browse/home/shop_mac/family/macbook?mco=MTE3MjE The spec I'm thinking of getting is; 2.4GHz Intel Core 2 Duo 2GB 667MHz DDR2 SDRAM - 2x1GB 250GB Serial ATA Drive @ 5400 rpm SuperDrive 8x (DVD±R DL/DVD±RW/CD-RW) So as you can see, the only customising I'm doing is increasing the hard drive. But, if I were to get 4GB ram, would it reduce the chances of any of those problems taking place? Sorry if I sound like an idiot but would more RAM mean it's capable of handling more stuff without extremely overheating? e.g. If I were to carry out my tasks using 2GB of RAM would it produce more heat than it would if I were to run the exact same tasks with 4GB of RAM? Also what advantage does the 2.4GHz have over the 2.1GHz? sorry again but I'm clueless as to what GHz do.
