In MBP I could boot to use the 64 bit kernel from this I have to check if firmware supports it by entering below in Terminal

ioreg -l -p IODeviceTree | grep firmware-abi

If the return is 'EFI64' then I just need to boot by pressing the '6' and '4' keys together while starting up.

After trying Windows 7 x64 bit with Office 2010 x64 bit public beta I just couldn't see much difference in performance. There is also printer driver support problem if I run Windows 7 x64 in the office. However it looks like that memory utilization is slightly better in OS X running 64 bit.

Now if you want to boot into x64 all the time you could modify this file

/Library/Preferences/SystemConfiguration/com.apple.Boot.plist

to insert this between 'string' tags

arch=x86_64

Before you do the above first of all you'll need to gain root privilege into your MBP. Haven't done this before here's the way.

Glossy LCD screen isn't good for the eyes so I bought below, Moshi iVisor protector

I have never used bluebooth mouse before.

It's particularly good if you feel 2 USB ports aren't enough and you didn't bring a hub with you. Bluetooth requires no dongle and most notebook will support it.

I'm very pleased with the touchpad on my new MBP especially the gestures using multiple fingers. Well once in a while a mouse is better.
