Dashboard discussion

Throughout the lifespan of the 360 we have seen 5 dashboards now. Each dashboard added something unique to the system until the last one. Do you think the blades dashboard would've been able to look good with all the added stuff? How slow would the blades dashboard been with all the added apps and what not? Did you ever notice differences between the online and offline dashboards like the newest one throughout the years (a side from the ads not loading)?
