Replacing PB 12" with mini?

Hey
I have a PB 12" rev A, my first mac. After more than two years, it's getting a bit old and I am looking into my options in replacing it.
My issues with this machine are:

• an almost dead battery
• A too small a screen
• Does not always wants to boot
• overheating of the HD (left hand palmrest)
• extra (cheap) ram is not always recognized on boot</li>
• A bit too noisy

I have put up with it the last half year, seeing it get worse and worse or alternatively running out of patience.

Ideally I would buy a PM 2Ghz with an DVI screen. But at the moment, being a newly graduate scientist waiting for that first research position to come through, I don't have the money for that. I could have that kind of money in a few months time, say january.
To spread out the cost I was thinking of buying a screen now, but my PB doesn't have a DIV-out. But the mini has.
If a sell my PB and spend a bit more of money I guess I could buy a mini together with a screen. And replacing the mini with a PM in a few months time. But is it worth the extra money to replace my PB with a mini, based on specs? The sentiment is that I want to replace the machine (while I can still sell it) before it completely breaks down and that I want something new.

On the issue of portability, in my case I have to drag my mac from my dormitory to ..., spending days to a few weeks at the alternative location. But wherever I go PC's are already available, but I prefer my mac. So for the 10 minutes or so it takes to setup a mini, I might as well drag that with me.

 

Ok, I'll order a screen with dual output mode (didn't realise Dell had that) and wait for the mini rev B, as I am no longer buying rev A, that's for sure. Rev B should be here by the end of the summer (Paris), I think. But hopefully sooner.

When I have a job, I'll buy a PM. By the time the intel stuff is working well, I am ready again to upgrade that PM.

If my first job is that research position, I'll ask for a PB 12" for normal portability (congresses, short trips) at work. Most likely I'll keep the mini for extended portability, so I can connect (by internet) it to the PM at home, or I'll just hook it up to the TV. The calculations I had to do for my graduating paper lasted a month.

I don't have the money now for something better than a mini, as I want a good quality screen to protect my eyes. The 12" screen for daily use was good enough two years ago, but not anymore.

This sounds like a good roadmap. Yvan256 en Jessica, thanks for tipping me over the edge.
