The perfect laptop...

Here is what the perfect laptop would have:

1. Instead of a battery pack, a battery bay where the complicated bits of a battery (the power management unit) is built in, but the rechargeable cells are easily replaceable. Laptop batterys consist of a number of Lithium Ion cells (usually 3, 4 or 6, but can be 9) - and guess what? They are AA battery profile. There is no reason laptop manufacturers should be able to charge $100 for a new battery when you only need to replace the *cells*, and the cells are not that expensive.

2. A not-too-widescreen. The way we're going, it'll be 1600 * 50px before long! For reading, a greater depth is better; 1366 * 768 is a step backwards (from, say, 1280 * 800).

3. A slight hump/lump/bump on the bottom to raise the laptop up, to allow airflow into the CPU.

4. Replaceable CPU.

5. BIOS that allows you to charge your battery to 80% instead of 100%; this will dramatically increase the lifespan of the battery (charging to 100% and draining to 0% kills a battery very quickly!)

6. Power connector at the back; USB on each side towards the back and 1 or 2 on the back; network cable on the back; HDMI at the back of one side or on the back; nothing on the front of the sides, within 3-4 inches of the front

7. Two speakers that aren't completely tinny (tinny is ok, but really tinny is bad!)

8. Power button on the side - so you can power the laptop up in "clamshell" mode (ie with the lid closed).

9. Two mini-PCIE slots - one for the usual WIFI/bluetooth, one for 3g or whatever else, and with the ability for it to be a graphics card (!).

10. And to round it off - not too heavy. Preferably 13.3 or 14.1 inch.

Obviously a non-crap keyboard, trackpad and so on would also be nice!
