I couldn't agree more.
All the memory/CPU space taken up by the ALG mode "capabilities" could have been used to add additional functionality or programmability for RPN users.
Take care.

PS - If two of us agree, does that make it $0.04 ?
PPS - I believe CN means China (place of manufacture). I'm not 100% sure what the numbers mean, but I think the 404... machines are from the first "run" which were sold through Walmart.com in late-February/March 2004; the 414... machines appear to be from the second "run", which arrived mid to late April; just in time for a lot of the NCEES test takers to not be able to get ahold of one for the test... or something like that.

My first batch "Walmart" unit is also CN404....
It appears that the first batch used the “ccywwnnnnn” serial number format, where:
cc = country of manufacture (CN for China)
y = year of manufacture after 2000
ww = approximate week of manufacture (I have always postulated that this was the week that the first units of a production were made, then they stuck with it until they made 99999 units, at which point they incremented the week code to the then current week. I have no proof, just a theory.)
nnnnn = 00001 to 99999 sequential count of units in that production run.
The second batch of units seem to have adopted a new serial number format of "ccAywwnnnnn" where:
cc = same as above
y = same as above
A = ? (I believe it has been postulated that this would indicate the decade of manufacture in the 21st century, but it seems like it would have been better to go back to a two digit year code)
ww = same as above
nnnnn = same as above
I don't have any thoughts or theories on the bugs.
