No vector icons. OK, bitmaps are usually large enough. But are they worth looking?
Iconfactory, the creators of original XP icon theme has made a lot in order to give Vista a brand new look. However, what we actually see is far not as good:
Just compare the same computer’s icon from Iconfactory portfolio with the one from an actual Vista.
The reason, I suppose, is simple: unwilling to pay for a complete icon suite from Iconfactory Microsoft has just taken a sample set and made the rest by its own designers (obviously far not that skilled). As a result, we see lots of elegant and nice looking icons (like Recycle bin) aside with ugly, blocky and aliased ones you’ll unlikely wish to enlarge.
