However, I do recommend the Samsung X05! Top Marks!

Overall, I have found this laptop sufficient. But for the price I paid I was very disappointed with its performance. My Samsung X05 laptop has been sent off 5 times in 3 years (1 time within the first year and 3 times recently), and in general it's been a downhill slope with performance.

Samsung X05 is a very good Notebook PC for business

I wanted a laptop computer for the portability, but i had a previous dell laptop, which was slow and bulky and battery power was a nightmare. But due to laptop technology advances, this Samsung X05 is like a greyhound with the sh*ts.
I have the 1.5ghz Intel Pentium M processor, with 512mb ram, it has a cd/rw drive, XP Pro as standard, it has intel centrino mobile technology, so is wireless, it weigh's 4.4lbs and can run upto 5hrs of standard battery. USB and firewire, sipdif for dolby 5.1, built in modem and a 40gb hard drive.
So impressed with it, i sold me top of the range desktop and bought another one, for the wife to use, so we both have our own computers now.
And because it is wireless, i bought a wireless netgear router and we both can surf the internet from anywhere in our house, using the one internet connection. Great product.
