I hate running 3 different chat clients (yahoo, msn, gtalk) on my machine – and that’s just 3x memory, startup programs and useless adversting too many.
And I hate msn and yahoo’s advertising that’s built into their clients…esp on MSN which insists on opening a mini page on login…
Use GAIM – and do yourself a favour. Of course that’s if you don’t need the very specialized features :)).
Installation is a breeze and use plugins you like and avoid the bloat….The best plugins I like are guifications and text replace. Lastly, if you keep moving between machines as much as I do, then its a breeze to retain your settings between all your machines.
