After few weeks of waiting since the death of my Acer 4520 machine and now having the new branded machine Dell XPS l140x with 2 Gb extra memory. I have been using this machine for some days and everything looks fine from the out part body into the real inside spec. 100 % satisfied.
I have tested my java testing and look promising, I used all the latest version of my development set and everything just gone fast and smoothly.
Finally just want to thank to Allah that He give me this new brand laptop.
