millions of dollars based on obviousness

I was hoping that someone more educated than I might be able to comment on Patent 6289908 for me. I am from NZ where this patent was invented. I have family who own one and recognise it is good - But; from reading the patent, it seems remarkably 'obvious'. It seems to me that the sole and only claim for this patent is that the dishwasher is essentially two small dishwashers instead of one large one. Your comments would help me clarify my thinking for my own patent - which is not a three drawer dishwasher (would this then be patentable if having two drawers is patentable - surely I could point out the numerous advantages of a three drawer eg one drawer specialising in glass, one heavy duty, etc etc).

US patent 6,289,908 expired on 19 October 2005 due to non-payment of maintenance fees.  The PAIR site does not list any re-examination or other activity that killed the patent; still it may be worth investigating if there was any litigation or other legal activity that rendered the patent moot.
 
If you are developing new dishwasher technology (or any other technology) be careful what you write in a public forum.  You may be weakening your patent rights.
