Go with the IBM. In my place of work, IBM's are loaned out to our customers and they really suffer every bumps and bruise you can imagine, but they are still going. I have owned for like two days the XPS M140 (the twin of the 630M) and it was a POS. It's like hit or miss to get a good screena nd overall build quality. But I still like my 8600 Inspiron and my new 710M. 









A big upgrade for me from my shitty laptop! Thank you all for your help and I'll keep you posted how things turned out.
