All the search results open an Amazon webpage with Canonical's Amazon Affiliate Code, which adds a tracking cookie to your session and makes Canonical get back an undisclosed percentage of all your Amazon purchases, as long as that cookie stays there.

It works fine for me at least, though it loads a bit slow. Has all the features you describe except calendar integration, but you can get that by using Kontact (which gives access to both Kmail, calendar and contacts in the same interface). Integrates with KDE address book, syncs with Google contacts/Google Calendar, PGP+S/MIME encryption/signing, modern UI, import/export, Sieve rules editor, modern UI (threaded message list, though no Gmail-like threading).

Sorry, meant to reply to the above post. Gmail is not written with the Google Web Toolkit, but other Google applications (which can be considered "modern") are.

Google Web Toolkit.
