The most remarkable part of "web apps" is probably what they do not improve on:

Smalltalk had (has) messaging and decent object orientation (and you have that especially in latest js) - but Smalltalk never had one standard vm implementation - different versions had different image (ram-saved-to-disk, source code and byte-code) and vms. Javascript has common source code, but no common vm/image format.

Office Suites had rich documents with smart(ish) widgets, but no security - a macro in Excel had access to all your spreadsheet data. Web apps don't really have any good encapsulation either -- so we'll likely repeat the macro-virus era with web virus era (I'm not sure if we already are or not, there's certainly been a few self-replicating ones, that eg spread via facebook updates etc. Not sure if they generally live in the phone-apps or various web-apps. Probably both).

We already had the future of web applications within reach years ago - but apparently no-one cared: http://lively-kernel.org/
