>Of course the author also said "The 7135 runs Palm OS 4.1, for which a large variety of applications is available. While Palm OS 5 has begun shipping on devices from Sony Corp. and Palm Inc., it's not certain that Palm OS 5 will displace Palm OS 3.x or 4.x during the 7135's lifetime, if it does at all"

He didn't mean that the 7135 will be able to run OS 5, he meant that because it runs OS 4.1, lots of apps are available. And, because OS 5 may never displace OS 4.1 in the general market (i.e. what developers target), the 7135 will continue to run most new apps developed for Palms.

Hope this helps.
