A04 & A05

[slam525i]

This topic's come up a few times and I just got my replacement from Dell (the built-in storage disappeared) so i have an A04 and an A05 sitting side by side. I can't tell the difference at all except the A04's D-pad seems spongier. The A05 gives slightly better tactile feedback and doesn't move quite as much but is still spongy. I don't think it's as much a difference between the A04 and the A05 as it is just poor manufacturing standards / inconsistent quality. Just thought I'd share with you.

Anyone else notice any difference between these two revisions?
(Note, this is NOT the software revision number. Anyone who speaks up saying they only have the A00 will be pointed and laughed at. :P )
