I still remember the times when there was only limited amount of disk space available (hard disk sizes of 20 MB were common), so keeping files as small as possible was most important. This prerequisite has gone, but there is another one: not everybody has a high-speed web connection!
Sure: T1, cable, DSL, these all are widespread, but what about mobile web access? UMTS offers top-speed, but when you come into an area not covered by UMTS, you’d have to fall back on GPRS or EDGE. How long do you want to wait for a web site to load on such a connection? Good. Then you know how important it is to offer light-weight versions of websites.
What do you think about this? Let me know.
