How much difference can you see (menu lag, boot time, multi-tasking, ect...) when comparing 32 MB memory (4 MB SRAM) vs. 16 MB memory (2 MB SRAM) ?

I don't notice much difference at all(7280 vs 7290). Main difference is in storage capacity.

I agree with Roofus. I do think that 4.0 will stress the memory requirements quite a bit....

You think? I know. I honestly think that 16 megs is an absolute MINIMUM for OS 4.0, it hardly gives a useful footprint of free space for storage of more applications, pictures, or e-mail..

i'm definatfely looking forward to upgrading to a 32 meg (or higher) device in the near future, perhaps though by the next model after 7290.

Anyone know of anybody hacking these things to increase the memory?

That's for starting my day off with a smile. No, I don't think there are any memory hacks.

We run OS4 .185 with idokorro mobile admin package and verichat and have more than 3mb left. That's with about 20-30 pics stored on my device and an avg of about 300-400 emails. That doesn't seem too bad to me
