I carry too many devices

Some all the time, some only when I need to:

• mobile phone
• audio player
• PDA
• car remote, several guarage door remotes
• USB drive
• headset
• notebook or TabletPC
• digital still camera
• digital video camera
• at some point: GPS

My ideal portable device will have all the above and more:

• it will be one and only one
• a lot of storage space to take all my media (100GB maybe?)
• high-res, high-zoom still and HD video camera
• 3CCD
• a good media (A/V, photos) player
• good-size, high-rez screen
• advanced PDA functionality
• good VoIP software; switches automatically from GSM to WiFi or WiMax
• comprehensive connectivity (WiFi, bluetooth, 3G, WiMax?, wireless USB)
• replaces other devices (home remote controls, guarage door controls, car keys?)
• integrates with my smart home systems for remote monitoring and control.
• a good wireless headset (which I can use for any audio device around me: TV, PC, etc.)
• more far fetched: I can use it with ATMs, POS and ticket counters at theaters, museums.

I will be while until even some of this wishlist becomes true, as this requires so many haedware/software development breakthoughs and corresponding catch-up from service providers and location owners.

P.S. I also use too many tools to manage my media: a few for photos (picassa, Adobe PhotoShop Album, Flickr), one for audio (Windows Media Player), and a couple for video. I want to be able to manage them all from one and only one tool.
