Macworld, the biggest showcase of Apple products and services in the world, kicks off next week and the computer world waits with bated breath for showman CEO Steve Jobs to announce this year's product roll-out. 

It will be hard to match last year's iPhone launch, however, and industry analysts believe this year's roll-out will be aimed at improving existing products rather than inventing new ones.
Widely expected is a new MacBook lineup, with smaller form factors and solid state memory.
Jobs is also expected to spend some time talking about how customers will be able to rent movies through its online iTunes store.
