Nokia :: Which One To Purchase E71 / E72?

I'm just about to purchase a new phone and would appreciate hearing anyone's advice on whether to buy the Nokia E71 or E72. I'm an Australian based photographer and will be using the phone for business and personal use and have decided on the E models because of their apparent success with email and internet capabilities. Main uses and features I need to work properly will be:


- Pop3 email acess for Yahoo address (with email client installed?) (Email is a major priority)
- Web access/flash based websites
- Alarm facilities
- Calender/reminders etc
- Opening/creating PDF and Word docs
- Maximum battery life
- Speakerphone
- Facebook access
- Texting (this is why I'm keen on the qwerty keyboard)

I've heard a number of good and bad things about both models (there are a considerable amount of complaints out there about the E72) but I'm bot sure which to decide on. Do either/both of these models read flash based websites? Apparently the processor in the E72 is twice as fast as the E71? And the data connection is faster? I've also heard that the E72 freezes a lot and the spacebar hangs and the phone needs rebooting... Are these errors likely to be rectified when firmware upgrades come out? How do I know when upgrades are available? I havfen't had a new phone for about 3 years so I have a lot of questions! Where can you install applications from and what sort of apps are compatible with these models?
