Even a UB Rev app is much smaller than many Mac apps for a single platform:

Adobe Reader 7: 84MB
iCal: 12.3MB
iPhoto: 36MB

Even Apple's Calculator, which was about 32k in Classic, is 2.1MB in OS 
X for PPC.

The difference is often the collection of non-code elements in these 
apps, with things that used to be efficiently stored resources now each 
a separate file within the bundle, bloating the total size according to 
the FAT minimums.

Thankfully Rev keeps such resources to a minimum, giving is a relatively 
tiny standalone by contemporary standards.
