Hello, please help me in choosing a laptop. I would not consider a Sony or Acer.
I need a 13.3 ~ 15" laptop/notebook,
windows 7 PROFESSIONAL OS (be it pre-installed or comes in a CD for upgrade),
4gb DDR3 ram,
@ least 320gb hdd,
3 usb ports,
a dvd drive
and my budget is around SGD 1.8k
Microsoft does have an official Windows 7 Support Forum specifically for IT Pros located here http://tinyurl.com/7jq7ps . It is supported by product specialists as well as engineers and support teams. You may want to also check the threads available there for additional assistance and feedback.
