Almost 2 months back, I got myself an ipod shuffle. After using it for some time, I am totally in love with it. I can now understand why the Macheads sell out their souls to Apple - the bargain is well worth it .

I was thinking about why portable devices like ipod and mobile phones are so close to their owners and I came up with this list.

• They are truly personal. You can customize them (think mobile wallpapers, ringtones, playlists) quite a lot.
• The are small and portable (duh!)
• They can serve multiple purposes. A mobile phone can also serve as a watch, address book, radio, m3 player, camera. A ipod can also be used as a memory stick, FM transmitter and it can also fit in your car's music system.
• These devices become useful as soon as you buy them. You can start using a mobile phone as soon as you insert your sim card into it and you can start using your ipod as soon as you transfer music into it. Instant karma!
• They have long battery life.

This list is just something to keep in mind when I am designing my Killer App (TM).

If you have not heard about emacs registers, you are missing a very powerful tool in your arsenal. Think of registers as "clipboard" on steroids. I had been using registers to store text -i.e. C-x r s a to copy region into register "a" and C-x r i a to insert text from register "a".

Today, while reading the gnu.emacs.help newsgroup, I came to know that you could save your current (emacs)frames layout to the register and then restore it back again.

• `C-x r w R' Save the state of the selected frame's windows in register R (`window-configuration-to-register').
• `C-x r j R' restore a window or frame configuration stored in register R.

Here is the email where I saw this.

C-x r w <some letter or number> to store a window layout and
C-x r j <the same number or letter> to restore it. And there
is no need to kill the compilation buffer.  It gets reused
anyway.
