As I commented back then on the Nokia Messaging blog post, the irony of this limitation is that whenever you delete one of your 100 emails, then it downloads again email #101 which it just deleted - what a waste! Especially annoying when that older email was unread, so you end up being notified twice.

All this said, I tried configuring my gmail account directly within the email client, but it would not be half as reliable as Nokia Messaging. If only they allowed users to:
- choose how many emails / days worth of emails to keep on the device
- choose whether to automatically download pictures & attachments

But they don't seem to be receptive - and given it's a server-based service, and not a software for the N900, it's harder to push the issue to the developers...
