(as someone who is very heavily using AJAX) that’s - IMO - rubbish.
[]AJAX needs no client
[]AJAX works on every browser, even mac-IE, even Safari
[]AJAX has no big download
[]AJAX only requires you know how to write HTML+CSS
[]AJAX has low memory requirements
[]AJAX does NOT force you to use a complete piece-of-sh** server thats useless for everything - it’s just plain old (X)HTML.
…just for starters.
PS: when I said this was all done before and/or being done, I meant the INTELLIGENT integration of document editing into HTML browsers, not using special clients and VM’s. You can do a lot with a word document whose native file-format is XML (this is how OO stores word docs), especially when you have smart pipelines set up for auto-export to PDF, PNG, etc - and can use simple WYSIWYG editors to do editing to the same level of quality as a moderate word-processor and using AJAX you have autosave.
I have a spec sitting on my desk for doing an offline version, that will work for people with laptops who keep disconnecting and reconnecting to the corporate VPN. Looks like it will work great, it’s just a question of whether we have the time to implement it, or if an off-the-shelf alternative becomes avaialble soon enough we dont need to.
