I can tell you some stuff about Macs.
First of all, I am using the 2nd Generation of the MacBook Pro, the 2.16Ghz, not the new 2.2Ghz. I have had it for many months now, and I can tell you, it is great for video editing and gaming (gaming works as long as the Halo servers work LOL) as well as everything else. I have done it all with the MBP, so if you decide to buy one, you should not regret it.
I have 2GB of RAM in mine, and I have had no problems whatsoever. Video editing and gaming require a lot of power, but 4GB is a lot unless you are running too many programs at once. I live in the States, so I don't know how much 140 pounds is. Here, 4GB is also expensive, so the 2GB standard should do well. However, if you need more than 2GB, but can't afford 4, buy a 2GB singles memory stick from a third-party vendor and replace one of the 1GB sticks in the MBP. They should be somewhat cheap. Then you get 3GB for nice performance.
Now I don't understand why your current MacBook would overheat and "throttle back". My MBP occasionally heats up on the bottom, but performance never suffers. You could download the iStat widget from Apple's website which monitors all your computer's functioning parts. When my laptop heats up, the fans start to do their part, but iStat tells me how I'm doing. Even if one app takes a lot of power, my MBP still can handle at least two other apps alongside one. For instance, I occasionally use iTunes and iMovie so that I can jam out while editing my movies. I also run Safari to download video and audio clips to add in to the movie, so I end up running 3 apps easily. The third version of the MBP should work even better for your needs, so don't fret.
If your MacBook messes up like that, maybe you should take in to your local Apple Store. I heard from one of my friends who works at my Apple Store that a guy ruined his MacBook by attempting to run the new Final Cut Studio suite on it. MacBooks are designed for more casual use and users, unlike us.
MacBook Pros come with a VGA to DVI adapter. I keep my 17 inch HP monitor hooked up for mirroring so that when someone comes into my office, I can show them what they need on a separate screen, and control what they see. This however, would only mirror your MBP. It would change your screen resolution to match the external screen, and display the same image on both.
If you mean that one image is shared between the two screens, then I do not really know. I haven't tried that yet. I just use this to have a separate display for my clients so that they do not have to look over my shoulder when I show them my videos. And resources? I'm not sure what you mean, but you don't need anything extra to mirror screens and power and performance are still going to be good.
I prefer glossy on my laptops just because the colors come out better on my games and my videos. Sure, light can affect it in certain areas, but I tend to use my laptop in preferred conditions. Matte reduces glare and such, also reducing vibrance, but if glare really bothers you, try matte.
I've heard rumors of a 12 inch MBP coming out later this year (though I kind of doubt it). I've also heard that Apple may introduce a new line of laptops and iPods in December after Leopard comes out. My advice is to know exactly what you want before getting it. I bought mine a month before the new revised MBP's came out, but that;s because I needed it. If you need it now, go ahead and it get it, but just be warned: Apple releases new products much quicker than most companies, so these rumors of new laptops may be true.
I hope you figure out what you need from this. And since you're from the UK, tell Paul and Ringo that THE BEATLES ROCK and that I love the new album (LOL). Yeah, I love THE BEATLES and all bands associated with them. Check my profile, it's funny.
Hope you like your MacBook Pro.
I?m from the uk but I decided to post here because of the larger forum base.
I?ve been looking at medium spec of the macbook pro ? 15inch screen, 2.4ghz core 2 duo, 2gb ram, 160gb hard drive, super drive and NVIDIA geforce 8600m gt 256mb and I?ve got a few questions about it that I need answered before I commit to it.
1. I was looking at 4gb of ram from crucial ? I will be using the computer for video editing, gaming and general usage ? is it worth it for
