There still exist connections as slow as 33 kbps. At that speed, 142 MB take 
at least 10 hours to download (probably more because 1 data byte takes more 
than 8 raw bits to transfer and because the theoretical speed cannot always 
be sustained). Depending on when you started the download (which takes a few 
days overall), that can mean you lose an entire day (if you are not lucky 
enough that those 10+ extra hours are overnight).

Most end users will not notice their one-time installation being a couple 
minutes slower.
