I will be streaming stock charts (one window only) and have about 6-7 other tabs open for email and general internet work. My two year old Core 2 Duo MPB with 4GB RAM handles this task just fine. Any thoughts on whether the Ultimate Air with the 2.13 GHz processor and 4GB RAM can handle this very very well? It's my understanding that the SSD helps with internal/local processing but I'm not sure about the internet/streaming capacity. The internet connection will be good. Thanks for the help.
