Microsoft, What are you thinking?

Just thought I'd blog today since FireFox 1.0 was released today, not that anyone is paying attention as Halo 2 Madness sweeps the country. But why is MS not jumping on the tabbed browsing bandwagon? It definately makes things alot easier than having a bunch of IE windows open having to go to the taskbar to switch between them. I expected tabbed browsing with SP2, but no such luck. Until then, I won't be switching back to IE.
