Have you tried updating to Android 4.0/Ice Cream Sandwich? the ICS Browser has many enhancements that seems to have been taken from the Android version of Chrome, like tabs. Its been fast and stable for me. If there isn't an OTA update for your tablet, there should be a good rom to use on xda-developers.
I use ICS Browser+ a browser built on the stock ICS Browser, with added functionality, like the ability to remove the normal menu and use a semi-circular "quick-controls" menu that pops up when you slide your finger in from the left or right side of the screen.
You mean this kind of friend?
Microsoft DOES do it, just not with Windows, but with the Xbox 360. When a JTAG exploit was found by free60, Microsoft fixed it just before they released the exploit to run homebrew and unsigned code. The fix? Use a new bootloader and blow a fuse on the CPU dye that was part of the old bootloader, nullifying the exploit. Unfair and shady? Given the possibility of a real brick if the dashboard update failed, you betcha. Illegal? Not so far as I've seen.
Surprise due today. Also the rent.
