Nice monthly poll subject, and thanks for the mention of my "Rate the PC above you" thread.
Bought my laptop in May 06.
2GHz AMD Turion MT-37, X1600 Mobility 256Mb GDDR3, 1Gb RAM, 15.4" glossy 1280x800 widescreen, DVDRW drive, 100Gb 7200RPM HDD, XP Pro SP2.
Plus some extras - Creative SB Audigy 2 ZS Notebook, Logitech G5, Icemat 2nd Edition, Logitech X-230 2.1 speakers.
Regretted it ever since, it's had nothing but problems the whole time and has currently been at the workshop a month waiting for a replacement lid after it cracked open.
But it wasn't my decision - my dad decided I didn't have enough room for a desktop, however with assorted external drives etc this laptop takes up far more room than any desktop could . . . anyway, long and bitter story.
Suffice to say it was OK at the time, and I wish more and more every day for a desktop PC.
