STARLESS72  I've used Vienna for quite some time now, coming from NetNewsWire, and I'm very happy with it.

But now, on my new i7 MacBook Pro, I discovered that it activates the NVIDIA video card as soon as I launch it! Definitely too much for an application which I always keep running in the background and which has no use for the dedicated video card. Time to switch to anything else? Unfortunately I tested NetNewsWire and it has the same behaviour.

WOLF3175  i'd like to let anyone know who is updating vienna or installing it for the first time and using 10.4 as i am be advised that this version (2.5.0.2501) is listed as being usable with tiger here on macupdate. i downloaded this update from here and realized after i had replaced my older version that it wouldn't open in tiger anymore. i came back and downloaded one of the related links to get a working version of vienna back on my tiger machine and when i opened it was informed that the newest update requires 10.5 to run. just wanted to put this out there and let macupdate know so they can update the application's page here.

DONMONTALVO  Beats NetNewsWire hands down...and it's FREE! I know some developers cringe at the later point. Expected. I've tried Gruml too, and I think they're both excellent options.

IVANOVITCH  I'd love to love Vienna, but from time to time it confuses and jumbles feeds (placing some news items in other feeds, dropping other news items altogether). I only wish that it was better than NNW et al, if only because it isn't placing gratuitous advertising all over the place.

But considering that it's free, I'm happy enough...

XCO  After five-years, I just now switched back to NetNewsWire from Vienna. The latest Vienna versions are VERY, VERY slow with my news feed database. Not sure why. But most importantly, I have begun using an iPhone news reader. I found having two different readers (Vienna on the Mac, and one on the iPhone) proved wholly impractical. I now synchronize all my feeds through Google Reader, and access these across platforms. Sorry Vienna.  
(Version 2.4.0.2401)

XCO  I find the latest Vienna hangs an awful lot at startup. I often must use a Force Quit.

This has not been the case with prior versions. I've been using Vienna for at least four years.

Also, the need to sink rss feeds between devices is getting pretty darn important, especially with my iPhone rss newsreader.

I'm running 10.6.2 on a late 2008 MacBook Pro, and 24" Apple LED monitor.

SW_TESTER  i figured out that Vienna had 29000 articles. NNW only 2000.

Apparently there is no option to keep articles "until they disappear from feed".

so in prefs you must set "move articles to trash" to something because "never" will cause issues. i prefer the way NNW does it.

what if you don't want to move articles to trash after a month for a feed that has older items?  
(Version 2.4.0.2400)

SW_TESTER  I wanted to switch from NNW 3.1.7 since I read the new version of NNW added adverts.

Also, I like to use open source when possible.

Vienna stalls and becomes unresponsive for 1 to 2 minutes when starting up with a spinning beach ball as it gets the feeds. Very irritating. I have only 30 feeds.

NNW only takes 5 seconds to get the feeds and does not become unresponsive. I don't get why Vienna stalls.

I have dual cores and OS 10.5.8.

Maybe it does not like the feeds imported from NNW?

MRK  Long-time NNW user, switched to Vienna a couple of months ago. This update addresses pretty much every problem I've noticed since then. Really great work.  
(Version 2.4.0.2400)

ABELLE  Very easy to use, no problems, very nice work, thank you.
