If you like me, do not currently own a laptop but do own a Pocket PC, you can still use PocketBlogger to post new blogs onto your Blogger account. The only thing you need is access to the internet either via WiFi, Bluetooth over mobile or GSM/GPRS enabled Pocket PCs.
Its pretty easy. All you need to do is get the required files from here and download Microsoft .Net Compact Framework for Pocket PC. Note that there are no setup files, just copy the folder to your device.
Since I currently only have access to a RM5 prepaid sim card I would not be able to demonstrate the features here (the reason why there are no original screenshots). My previous testing with it while in London shows that it works even on WAP CSD connection.

The program only works with Blogger using Atom API. It is in its early stages and the author plans to implement LiveJournal support as well.
You can try other blog-based programs for Pocket PCs such as Pocket SharpMT and PocketBlog. These are more powerful but lacks the friendly GUI of PocketBlogger.
By the way you can always use blogger's e-mail service to post new blogs from any mobile devices although you would not be able to edit them.
