Laptop - Dell Studio 1558 Intel i7 - 720QM (1.6Ghz) - 4GB RAM - 15 inch, I purchased this laptop in March 2010 with the intention of using it as a portable machine. It is actually quite a bit heavier than I had expected and more suited as a desktop replacement where space is limited. It is in virtually new condition and I still have the original box. I have reset it back to factory condition and installed all the latest updates for Windows 7 Professional 64 bit operating system. It still has a Dell warranty (In home) for hardware which is transferable and valid until March 2013.
