Fastest Twitter (Desktop) App for Old Computers

My needs are simple. If an application/program doesn't cause my 4.5-year-old iBook G4 to lag, I'm thankful.

Tweetdeck is often cited as the best desktop Twitter app. Unfortunately it takes up way too much memory for my old machine.

DestroyTwitter, on the other hand:

..uses a minimal amount of memory compared to its AIR-based alternatives without sacrificing functionality and performance. As a result, it can easily run in the background as an automated process.

The only drawback is that it doesn't (yet) support multiple accounts.

I've been using DT since April 2009 for my business' Twitter account, and it is nothing short of wonderful.

My all-time favourite is the "Exclude" feature. DT had this long before Twitter lists rolled out. It helps me block out some of the noise (or rather, noisier tweeters) yet still appear to be "following" back my followers. It only blocks out their tweet stream; you will still be able to receive @ replies and DMs from the people you've excluded.

Another favourite is being able to select my preferred URL shortening & picture upload services; the list is not exhaustive but it needn't be.

If you haven't already, give DestroyTwitter a whirl and let me know what you think.
