Why does the offline RSS-client is better?

In light of the recent decision of the company to make its NewsGator RSS-client free for individual users began again discussion about what is better to read news feeds: using online services or programs that need to be installed locally. Nick Bradbury (Nick Bradbury), FeedDemon developer in his blog he led 8 arguments for desktop applications.

- Most online customers to read the RSS-streams have a serious drawback - they can not read the tape, password-protected. Such flows are actually not so little. A password is required to read "podzamochnyh" Learn records, paid subscriptions (eg, Daring Fireball before moving to the sponsorship model of selling subscriptions).

- Online aggregators do not have access to a stream being "behind the firewall". This is a rather unusual case. Bradbury writes about the internal server running FogBugz. Critical subscription Nick can not add to an online service.

- The majority of online customers are not able to work in offline mode when there is no access to the web. And those that are able (Google Reader in the presence of Google Gears plug-in installed) is still inferior to FeedDemon

- Many of the reading room are full browsers, providing access to the "Favorites" and allows you to open links in tabs

- Microsoft Outlook users can install NewsGator Inbox, and then in a mailer they can not simply read the RSS-feeds, but note flags interesting notes, indexed articles, filter them, archive, etc. - all that is able to Outlook

- desktop applications have access to local resources, which do not have online services. Therefore, many RSS-client are able to integrate with a blogging client, download podcasts and copy them to the iPod (or the WMP-device). And even NetNewsWire integrates with iPhoto, Twitterrific, Mail and iCal.

- Programs give you a choice - which subscriptions must be personal. FeedDemon, for example, can selectively synchronize the subscription, but not all.

- Another advantage, according to Nick - this is the speed at which desktop applications above.

"LH" on Statistics longer read using Google Reader (although the share of off-line clients is high enough). And I, frankly, many of the arguments do not seem convincing. What do you think? Why did you chose the online client or a desktop application?
