2003 SE critical updates?

[afratki]

Kind of a newbie question but I searched the forums and couldn't find an answer. I recently purchsed a used x50 and love it so far. Does the OS (2003 SE) need updates like my desktop OS? I already updated from A01 to A05 when I first got it but I can't find anything on OS updates. TIA

A05 is it unless you want WM5 woes.

A05 is it unless you want WM5 woes.

Was thinking of going to WM5 until I read about all the problems. Thanks for the answer on 2003 SE, I'll stop searching now.
