Did they increase RAM in iPad 2?

Solution 1:

Apple never releases information about memory. The current rumour is 512 MB. You should wait until some opens it up (e.g. iFixit).

And there you go . iPad-2-Wi-Fi-Teardown. 512 MB of Samsung manufactured RAM.

Solution 2:

You know, I know how much RAM is in the devices I choose as well. I used to be such a predictor of how well a device functions, but I have to admit that Apple's latest round of iOS devices make me not really care anymore. Why worry about when it functions so smoothly. I for one hope more hardware manufacturer's adopt this philosophy, "Make it work well as an integrated device, not as a combination of desperate gadets".
