I suppose, if I was Apple
I'd fit 1GB
It's apparent that now, 7 ish months after the iPad's launch that 256MB is starting to be an issue in some ways.
512 is on the current iPhone and I think we are all saying it would make todays iPad NOW all sweet and happy.
If we think we are getting a rear camera, it has to do video and then it's a given it will have an iMovie app.
So, given this, AND iPad apps are going to grow over the next year etc etc.
The next iPad has to have enough RAM fitted on day one to last for a year and half from today.
Plus you have Blackberry who are going to shout and shout and shout about their Playbook having 1GB of Ram.
If Apple fitted 1GB, sure it may not be totally 100% needed on day one (though I'd sure iMovie would not complain about more memory)
But it would stop any issues from occurring over the months next year and allow even more advanced apps.
Plus of course, it would stop the competition of using at as a weak point to the general public, as to the man in the street more and bigger numbers are better.
I'd happily pay a few dollars more to have the future proof 1GB of RAM rather than the 512MB
I can't believe in the millions that Apple are buying there is much price difference at all really.
We don't want to be at this time next year saying how the iPad 2 is struggling with it's 512MB and why didn't they fit more.
I just looked, the current 256MB of RAM cost $11.90 back earlier in the year.
