IBM Thinkpad R50P (1832-23A) >> Pentium M 1.7GHz | 1GB RAM | 60GB & 120GB 2.5" IDE HDD On-Board | DVD-RAM Drive (not inserted) | ATI Mobility Fire GL T2 128MB | 15" UXGA LCD (IPS) @ 1600x1200 resolution | GB Ethernet, 802.11b/g mPCI & Bluetooth | 10.8V 6.6Ah Battery | MS Windows XP Pro (SP2)

Have had this notebook for nearly 2.5 years (got it as a free replacement from IBM for my original Thinkpad A30P which had a lot of problems and ultimately died on me after 2 yrs), haven't changed yet because still looking for a notebook that can support 1600x1200 without weighing a ton
