I have had several issues with responsiveness since I last posted, however they have become fewer and further between. Each time I noticed sluggishness I would run the task killer and it would take 5-10 seconds to display its list. Once I killed all unused items the device became instantly faster. When I randomly run the task killer it usually displays its list before I even have time to think it's slow, less than a second and most times a full page is listed. I have minimal background processing: push email for a gmail account, facebook(30 minute updates), a calendar widget (1 hour updates) & a weather widget (30 minute updates).
