After performing a full format on my Windows Vista partition (I have a separate one for Linux), I reinstalled the usual Windows applications I use — specifically those software I use for freelance projects that doesn’t have a good Linux alternative. Obviously, I did not settle with my project essentials. I still installed my favorite time wasters; Instant Messaging software, games, etc. I installed the latest version of Google Talk and the Vista-version of Yahoo Messenger.

Choosing the “Yahoo Messenger for Vista” instead of the old version 8 (which had no ads embedded to it) I always loved was one of the greatest reversible mistake I did. Yahoo Messenger for Vista, was indeed, a crap — worse than the previous versions of Yahoo Messenger.
Yahoo Messenger for Vista is a memory hog (memory pig, memory hoarder). Running the program is almost the same as running a decent PopCap or Yahoo game. On a rather average machine, everything just turns sluggish once it logs in. But on a pretty fast one, it’s doing okay.
It has a trying-hard eye candy interface. The term trying hard is there as eye candy is not a right term basing on it’s definition that is visual images that are pleasing to see but are intellectually undemanding (wordnet.princeton.edu/perl/webwn). I bet Yahoo’s designers tried their best to make it as attractive as possible; but mind you I was never astonished by it. The heavy typeface applied on the items of the messenger list just suck, plus the bad choice of font.

The notification popups are no less than annoying. Previous non-Vista versions of Yahoo Messenger has this small notification popup whenever a buddy signs in or out. This feature has not been removed in the Vista version, but instead made it a lot bigger and more distracting. It just annoys me the way it is, I hope Yahoo would revert it back to the smaller ones on the next releases.
The visual effects were good. The effects are attractive and soothes the eyes. The windows are non-rectangular; unlike the typical windows we have. Translucency (partial transparency) is also evident especially whendealing with popup menus.
Most of the features are not outrightly visible. To change the chat text font, one still has to click the intuitive “A” font icon on the conversation window. To add a friend or perform other contact-related options, one still has to click the very unintuitive downward pointing arrow. Everything is unfamiliar.
Given all those observations, an assumption that Yahoo tried to concentrate on the visual appeal to the extent of compromising stability (yes, it’s unstable plus it’s nature of being a memory hog) can be concluded.
They should also consider putting the essential features outright on the window and not hide them behind menus. Yahoo should redesign the said application putting balance on the visuals and stability.
