Most of you probably know of this, but I just decided to make a post about it. And this is probably less than a tip.
This is tip is mainly for those people who use laptops for everything--home, work, school, light gaming, etc. etc.
I have a 12" laptop with the following specs: 2.2 Ghz Core 2 Duo, 2 GB Ram, and 128mb GeForce 8400 graphics card. I pretty much use it for everything. One thing that bothered me was that it got sometimes uncomfortable to use, when on it consistently, whether it be studying, essay writing, or even some light gaming.
So what I did to make it more comfortablet was buy addons for it. I bought it an LG wireless keyboard/mouse combo and a 20" LCD panel from Newegg. No matter what kind of keyboard you have on your laptop, a full sized desktop keyboard will always be more comfortable, and having a bigger screen to look at just feels good. The LCD panel hasn't come in yet, but whenever I am at home, I can just simply connect my laptop to the monitr and mouse/keyboard and just tuck my laptop away somewhere and just use the 3 addons. A LOT more comfortable than using a 12" screen with a small keyboard.
I might even buy it some speakers...as this laptop in some sense with its power is like a desktop replacement
