As for the dual booting thing, you could try using a virtual machine. Those things are awesome. As many OS's as you have memory and HDD space for. And if you do it right, set it up once. Save the image or profile of it, and if you have problems with it. Just delete the file on the main computer and copy over from the original and you have your OS back like new. You can even play around with whatever you want on it. Screw it up and just copy over from original and you are right back to a fresh OS. Quicker than installing a new one. As for building a laptop, if you want high end, Alienware. Low end can be a crap shoot but Dell is pretty good as well at that end. Or gateway. And yes, I know, Gateway sucks. But I have 2 of them, one of which I have have had since 07' and am still using right now as I type this. All I needed to do is upgrade the RAM to max and upgrade the HDD to something bigger. When I got my laptop I looked at the features and Processor cause the ram and Hdd can be upgraded easily. Something with an Esata (External Serial ATA) port and maybe an HDMI port. One of my laptops can take 2 internal HDD's which is a feature I love. If you are looking for the best bang for the buck. Look for one with a good graphics card and decent processor. But get it with the smallest amount of ram you can. Reason I say this is when you upgrade the ram, it's not like a desktop where you just add to what you have. You are replacing what you have. So you would be taking out what is already there and putting something bigger in. Hope all this helps. Sorry for the long read. My side work is specializing in laptop repair and upgrading. Just not much business for it since it's usually cheaper to buy a new one.:thumb:
