I cant live without my sidekick.
Here's what you need to know though:
you can only have 4 pop accounts on the device, plus the built in email address.
The webrowsing is excellent, except javascript, flash, isnt supported.
you can get the developer kit free, and upload your own apps.
goto
www.skdr.net to see what apps are available.
I have a weatherbug type program, a stock ticker, and rss reader, some games, an online chess client, a multi client messenger program (MSN, Y!, AIM), telnet client and more.
the Email client is excellent and the overall interface is sweet.
The camera on the skII is decent, the flash could be better though.
Anyone with a sidekick gets a free blog that you can post to via the email client.
check
www.hiptop.com
my blog is
www.tinyurl.com/exv3 if you want to see what the camera pics look like.
overall it's an amazing device especially when you get unlimited data for $20
also if you do website stuff, (design, ecom, porn, networking, whatever) you will absolutely love it!
