Try using the new OWB 1.23 web browser for a period of time, 512MB will not last you very long unfortunately. If you are getting crashes on the SAM440ep, then perhaps you are running out of memory? We have both machines in our office and performed many comparison tests: the speed difference between browsing is very noticeable due to the large horse power of the PA6T over the lowly 440ep.
A good test is the MACE game, the game can be played in 1080p on the X1000 without issues, on the 440ep it cannot, which is of course, to be expected.
Then we have AMIStore project which will soon be bringing bigger and better software releases to AmigaOS, These new titles will need more memory and more CPU power and better graphics cards.
I respect your viewpoint because you are not privy to the software developments that are happening right now.
Finally, the lack of PCI-e slots on the SAM range causes problems for the future if you want to expand. At the moment, A-EON is sponsoring development of new PCI-e drivers.
