My Top Free Apps from the App Store

1. Remote
Native app by Apple. Allows you to remotely control iTunes on your PC via WiFi (on iPod Touch).
Works really well - pairs your device with your computer using a randomly generated passcode.
Would be good if they expanded the capabilities of this app by allowing it to control your computer's volume (not the volume in iTunes) and FrontRow. Perhaps even Microsoft PowerPoint and Keynote support? That way, I don't have to use my Apple remote. I'm not counting on Apple to do it though.

2. Instapaper
Saves webpages for offline viewing. Great for reading my favourite sites when WiFi is absent.

3. ShoZu
App for uploading pictures and videos to popular social networking and blogging sites like Facebook and Blogger.
Could be improved but thumbs up for supporting multiple websites.
So far, I've only used it with Facebook and Blogger. ShoZu does not seem to allow stand-alone blogging without posting a picture first.

4. Aurora Feint
Right now, best free game for the iPod Touch. However, I can only play it once before it gets cranky and refuses to load. :S

5. Facebook
Function is similar to the Facebook web app for iPhone.
Extras: Supports comments, Facebook chat, changing of profile picture
However, this native app does not allow you to view your own photos easily. It would be nice if it allowed uploading of photos too.
Edit: It does allow uploading of photos, but not to your profile pictures.

6. To Do (By Erica Sadun)
Not the best GTD app out there, but it's free. I would prefer checkboxes to greyed out text, and the ability to categorise your tasks. E.g. Rent Movies>Shooter

Other Apps that I tried out:

Currency
Currency conversion app.
Not as good as the currency widget. Only allows changing values of the master currency, and not any currency you have added.

Holy Bible
It can't retrieve the Bible text if you're not online. Oh well.

eBay
App that watches bids on items, allows searching and bidding on items.
Refining of searches could do with more options, such as by country. Now I just get a mass of entries that ship to the U.S.

eReader
Reader to read eBooks.
Haven't downloaded any eBooks, but the demo ones work fine. Page flipping is cute - nice sliding animation.

Epocrates Rx
Drug database, complete with pictures and descriptions (e.g. contraindications). Allows for searching of drug interactions, specific drugs (by name, shape, colour etc.).
Works rather well, and updating the database is easy. But I suspect it won't be too useful for me as some of the descriptions are a little too technical for the layman to understand.

Tap Tap
A game like Dance Dance Revolution, except that you tap the little dots on the screen according to the beat.
Moderately fun, but not a very impressive game. Maybe I just don't like DDR.

Morocco
For Othello fans. Works well, but I suck at it. Option to show you your possible moves.
