Lenovo X201 to X250

I've had my X201 since Oct 2010. Win 7 Ultimate 64 bit installed since day 1...never had to reinstall the OS. Other than the once in a blue moon freezes, it has been running solid. It's been all over the world with me whenever I go travelling. Never had to use the 3 yr on site warranty I purchased.

I'm looking at purchasing an X250 when Win 10 final is released.

1. The non-removable 3-cell battery that's built in...I would think it will degrade over time due to heat from the laptop? I only have the battery attached to my X201 when I'm not near a power outlet. When my X201 is docked or near a power outlet, I take the battery out.

2. The docking station I have now for my X201, is it compatible with the X250?

3. I also read that people have been starting to successfully install a 16GB SODIMM into the X250. I would think price for that particular SODIMM will drop in summer/fall?

 

The cooling system is decent, and keeps the internals sufficiently cool, so the internal heat affecting the battery should be minimal.

The battery is also supposed to have a longer lifespan as it is Li-Po and not Li-Ion (at least it is in the X240, though the X250 might be the same).

 

No.

 

Memory does sort of an inverse bell curve when it comes to pricing. When it's new and there's not many manufacturers, the price is high. When it becomes the dominant memory type(most people are buying 4GB and 8GB sticks right now), the prices drop as there's more manufacturers making it and you get the economies of scale thing going on, competition too. Finally as it falls out of favor due to the fact newer better stuff is coming along, it stops getting made, but you've still got people who want it because they're not ready to give their machines up yet and want to upgrade them instead, which drives up the prices as there's little supply. I've actually sold memory for more than I paid for it as it was a few years old, but no longer being made.
