Hi,
After I got the Kindle, I looked around and realized I too share in the madness: wii, 2 reader (kindle and prs500) - 2 ipod nano household, 3 palms, macbook, Asus eee, a couple of old Dells, etc.
At least we don't have cell phones.
My advice echos others:
-listen to your significant other for reality check (marriage tempers finances)
-refrain from impulse buying when hungry, excited or bored
-pay by debit or cash aka pay credit card after every purchase
-another thing I found that works is wait 1 month or more with no forum visits about the product. At least you can hold off until the next best thing comes along.
I really wanted an ipod touch for the jailbroken apps -portable vim, but I waited instead and the craving went away. I also asked what would the gadget bring to my life other than a few hours pleasure that could be spent on existing gadgets I already have. Beside I think a new touch or tablet will be out next year. At least one can prolong the addiction.
I admit though the Kindle is a good fit for me despite the high cost.
My Asus eee doesn't get as much attention because the battery time is so low (~2hrs if lucky) and still hefty weight.
I can finally get lynx like text browsing like my old Palm VII which costs $399 and had a $10 monthly plan back in the web clipping days. Moreover, read books without eye strain.
There's not much else they can come up with unless a new e-ink tablet comes out where electronic paper is truly realized. No Livescribe or heavy 2 pounder 'ultralight', just a writable, searchable 10oz e-ink pad.
Then that will be my very last gadget, i promise
