Yetanotherdave, you were right to begin with.
Resolution as in pixel density (like original statement by yetanotherdave):
- The statement "The Apple iPhone has a better resolution (326dpi) than the iPad (132dpi)" is absolutely correct.
- The statement "The Apple iPhone has a higher resolution (326dpi) than the iPad (132dpi)" is also correct.
Resolution as in number of pixels (like the "correcting" statements by chrmjenkins and BaldiMac):
- The statement "The Apple iPad has a higher resolution (786432 pixels) than the iPhone (614400 pixels)" is correct.
- However, the statement "The Apple iPad has a better resolution (786432 pixels) than the iPhone (614400 pixels)" is incorrect since bigger isn't always better. An 1920x1200 24" display isn't necessarily better than a 1920x1080 24" display. A 21" 1600x1200 display isn't necessarily better than a 21" 1680x1050 one and so forth.
Furthermore, if chrmjenkins and BaldiMac really analysed the semantics of yetanotherdave's statement they would realise that he is right and they are wrong. He referred specifically to the HD suffix everyone adds to their apps. HD as in High Definition refers to a higher pixel density at the same given physical dimensions. A 1080p cinema is not HD (since the pixels would appear enormous), however a 480p movie on an iPhone is perfect HD. A correct usage of the HD suffix would be to add it once an iPhone application is Retina Display compatible.
