Thanksgiving and I finally have a break from school and time to work on other projects.

Evernote is my external brain. There is a desktop app for Mac or PC, an iPhone app and a web app that all sync automatically. There’s even a Thunderbird extension that sends things to your account. Text, audio, or photo. It’s searchable, taggable and has categories.

Bookshelf is an e-book reader specifically for iPhone and the iPod Touch. It supports a lot of file formats (no DRM), including all my MobiPocket formatted files from Webscription.net. The best part is the customization options. There are a number of color themes and you can set the font and the size for what is easiest to read for you.

Any time I mention e-books, someone goes “But I like paper”. I like paper too but paper is heavy and bulky to carry around. I can fit a dozen books on my phone, which is backlit for low-light situations and always have something to read when I have to wait. Plus, with Webscription.net’s free library and low prices I can save money and a tree.

Mah Jong is an old favorite game of mine and Moonlight is the best execution of it for the iPhone. There are several layouts and a free as well as a pay version.

Sudoku is popular all over these days and Big Bang’s web version for the iPhone was the most popular option. The installable version is still good, though there are a couple of changes I would like.

Yes I’m a Twitter addict. All my friends are too so it works out to help us keep up with each other. I’ve tried several different Twitter clients for the iPhone, including Twitterific which is my desktop client but I’ve only fallen in love with Tweetie. It loads quickly (moreso than the website) and gives you access to all the normal Twitter functions.

There are lots more great apps and I’d love to hear your favorites.
