Talk:Comparison of HP graphing calculators

48sx?
Why is the 48sx not on this chart? Is it not a full graphing calculator? Macduff (talk) 14:35, 17 December 2009 (UTC)

IrDA in older Models?
The table appears to list IrDA for all infrared supporting devices. IIRC only the newer models actually support IrDA while the older ones use some proprietary HP infrared protocol. —Preceding unsigned comment added by 95.114.50.194 (talk) 08:20, 17 July 2010 (UTC)

Why not an article like "Comparison of HP scientific calculators" ?
Wouldn't it be interesting ?
