Vlogging, Videoblogging and using a blackberry to blog

The blackberry devices are coming down in price, and I am seriously considering one..
But I have to wonder, does anyone blog form their blackberry? Is ther eany specific ups or downs to blogging from one?

Can you recive video on one? With Vidoeblogging, or vloging or is that vlogging? becoming more popular, I am really wondering, what video woud look like on one? Then can you patch a webcam or similar device into your blackberry and upload? Say I decide to video blog.. can I do that from a blackberry>?

Well that's my questions.. hoepfully some smarty pants will have an answer or two..
