My first laptop was this really crappy Proline TW3 Notebook. Had an Intel Core Duo 1.6GHz, 512MB DDR2 RAM, 60GB HDD 5400RPM, Nvidia GeForce Go 7400, 1280 x 720 LCD Screen. It had Windows XP, then I put Windows 7 and added another 512MB ram stick.
As for the first PC in my house, my dad bought one way back. It was this lexus PC Tower....had Windows 98 on it. It had a 250MHz processor, 128MB DDR RAM, 40GB Hard Drive, floppy drive, CD-ROM Drive.
Surprisingly, the PC was upgraded to Windows XP....yoh you had to wait for 5 minutes after logging into Windows, for it to be ready to open stuff. CPU usage was always at 100% on this PC....only game it could run, that I installed was Revolt (the racing game).
