are there people actually using GNUMail?

[Zhang Weiwu]

Because I don't think it is workable, yet it is included in almost 
every distribution and seems to have a fame.

It crashes when choosing to reply to "Everyone";
It displays characters in compose window at 1/2 speed I can type;
It doesn't support thread view (as Thunderbird has) or going to the 
next email in this thread (as Apple mail has);
It sometimes have wired behavior, e.g. typing 'i' after 'f' causes 
both letter erasered.
A lot of strange design. e.g. you have to do a "f-ind all" (you know 
why I type a dash between f and i) before using "Previous" and "Next", 
most newbie wouldn't get this (in case this is really logical, the 
button "F-ind all" should be vertically above "Previous" and "End" to 
give user the idea of their relationship.

Can those who actually use GNUMail nowadays post a message and share 
experience?
