I would publish a product routemap for the next 12-24 months so as to keep potential customers as informed as possible. The potential for other firms to 'trump' Apple on products would be offset by people happier customers imho.
I would put a mic and camera into the iPod Touch
I would deploy iChat on the iPod Touch / iPhone platform
I would put GOOD screens in all laptops, with more USB ports.
Put VGA adaptors and remotes in all laptop purchases as standard.
I would release a desktop mac using a Core i7 CPU (Xeon is a pointless expense on a single socket machine) with room for two HDD's.
Cull the AppleTV - replace it with a TV-centric docking port for iPhone/iPod touch.
Bluray AS STANDARD in all MBP's.
Get some frickin QC on new product lines.
Banish network exclusivity for iPhones.
Fix Keynotes exporting feature. Seriously - it's pathetic.
Produce an iChat client for PC's. (iChat Theatre is pointless when only 5% of people can receive it)
Competitively priced 20, 24 and 30 inch displays with calibration tools.
Dump the old, stereotype reinforcing and frankly, lie filled 'I'm a Mac' ads, and replace them with short adverts that highlight one home media creativity project instead. (i.e. import photos, make photo book. Capture video, edit, put on Youtube. etc etc)
Stop lying in iPhone adverts.
Fix audio hiss on laptops.
Fix Safari. Seriously.
Fix the Sync processes. Every 10 mins, my mac sticks at 100% CPU for a minute because of damn Sync processes.
Infact, fix MobileMe sync features all together. Very broken.
'Try a Mac' - leave a deposit and you can try a mac for a week. Like the 3 day car test drives.
Spend SIGNIFICANT advertising budget HONESTLY dispelling some of the Mac myths out there.
Spend SIGNICIANT time making sure advertising stopped pushing the smug arrogant t**t image they're doing right now.
Make a 10" netbook the same form factor as the Samsung NC10. Make it £300. Make it have 3G. Make it now. Watch the customers ROLL IN.
Higher res screen options for ALL laptops.
Stop taking the piss with HDD and Ram upgrade prices in the store.
Block facebook, bebo, myspace etc. in Apple Stores.
Fix the Apps store submission process. Reward your developers - don't make them jump through hoops.
Stop pretending that downloads are the short or medium term future of HD programming.
Stop charging more for a track/album/tv series/movie in the iTunes store than it costs to buy physical media.
Get rid of the frankly pathetic Windows bashing at developers conferences. It's childish. It's embarrassing.
Broadcast ALL sessions of ALL conferences, live.
Developers blogs for upcoming software and hardware.
Make me feel like a customer, not some annoyance.
