Its really a tough choice. They are both powerful packages.
Both packages have gone well beyond your current Minitab 10. I also have
to preface that I only have JMP 3.2 - I have not seen JMP 4 which has
just been released.
Both can do multiple regression about equally well.
Minitab 13 has pretty easy to use checkbox options to create...
-a histogram of residuals
-a normal probability plot of residuals
-a plot of residuals vs fit (y-hat)
-a plot of residuals vs run order (order in worksheet)
-a plot of residuals vs a specified variable
Minitab also allows you to save the residuals to do other plotting.
JMP 3 does an easy to obtain plot of residuals vs predicted (y-hat).
Beyond that I think you need to save the residuals and do your own
plots. JMP does allow you to save the residuals.
By "generate estimates" I'll assume you mean that it calculates
predicted values and the related error and confidence/prediction
intervals....
Minitab has an Options dialog box in which you can enter either
individual values for x1, x2, ... or you can enter variable names that
contain a list of multiple x1's, x2's, etc. The output includes the fit
(y-hat), SE of fit, and the confidence & prediction intervals (you can
select the confidence level).
In JMP you can save predicted values (probably includes any obs. w/
missing actual), SE of predicted, SE of individual, and confidence
(Prediction Conf.) and prediction (Indiv. Conf.) intervals. Pretty much
the same thing.
For exploratory data analysis they are pretty close. Its pretty much a
toss up.
One other thing if it makes a difference, JMP has a nonlinear fitting
tool; Minitab does not.
My own thoughts (I've provided both packages to engineers in the past)
in general is that Minitab is clearly easier to use for the occasional
user (not my opinion but that of my engineers). To get the most out of
JMP you need to be a fairly regular user, since many of its tools are
somewhat hidden.
