These are very biased news and in fact they are wrong. For starters, only the first submarine has a floatability problem. The other submarines in the series are larger, therefore they have no problem. Now, why has the fist submarine (the original design) a floatability problem? Because the Navy asked for more equipment (electronic equipment, weapons, etc) and more comfortable cabins for the sailors than originally planned. It is not a design problem but a modifications problem and this is very very very frequent in large projects, especially if military. The changes have been taken into account in the design for the second and subsequent submarines (S81, S82, etc). The first submarine (S80) will be fixed by making it a bit longer and adding some floating aids. Source: I work in this project. Next time you want to say stupid things about very serious projects, please warn us you are drunk.

If this is the case, then I don't see the point. Filesystems already in use support TRIM.
Just because you send TRIM down it doesn't mean that the device can erase the block. The erase block size in NAND is usually 256KB or larger. Using 256KB as IO block is just crazy, drivers use something like 16KB or 32KB. The filesystem has to be aware of the erase block size so it can send down TRIM command for an aligned and contiguous 256KB block, then the device can go on and erase it.
SSDs are NAND, but they are not bare NAND. They have control circuitry which manages the problems with NAND (e.g. bad blocks), and presents the drive as a contiguous block of good storage.
These filesystems are all for bare NAND, not SSDs, which include NAND, but are not bare NAND.
How can this be "Informative", it's plain wrong. f2fs works on top of block devices.
No. SSDs present themselves to the OS as contiguous block devices. Filesystems intended for bare NAND flash like jffs(2), yaffs, and this new F2Fs would be totally useless for SSDs. They're intended for bare NAND, which SSDs are not.
You're wrong
f2fs work on top of block devices. f2fs sends TRIM (ATA command) down to the device. Bare NAND flash doesn't grok ATA commands.
So the OP means: "Get an iPad so you can look like your grandmother" ! hmmm.
Does your notebook last 12h, 16h or 18h? An out-of-battery notebook cannot do anything.
at 21", it would be a tabletop and not a tablet.
1. It has the best (claimed) battery life (when used with the dock) 18h. Kal-El, with 40Mbps video capacity, should (in theory) handle any kind of HD video including BR rips. NEON+quadcore should be good for games (NEON wasn't supported in Tegra-2).
2. The 4+1 is transparent to the OS, according to Nvidia.
3. Linux kernel will scale and spread tasks among avail cores. whether a game will spread intensive jobs to multi-threads? well it depends on the game...
4. Do you play games all the time? well get a console then.
