I've lurked for a while, and am probably going to take the plunge later on my first ThinkPad. I've long coveted the X-series, and am very excited.
That being said, I'm having a tough time deciding between the 201 and 201s, and I'd like some feedback. As background, I'll be using this computer for computer programming, compiling, electrical design, and a lot of multitasking. I'm a computer engineering student going into my senior year, and on a couple of days I'll have classes from 9:30 AM - 6:00 PM, so I also need the excellent battery life that the 9-cell provides. The only gaming I'd be doing on this would be browser-based Flash games or game development with Flash or Valve's Source engine; nothing too ridiculous.
I've configured an x201 via Lenovo's site with the following specs:
- Core i7 620M
- 12.1" 2x2 screen with camera
- 4GB 2DIMM RAM
- TrackPoint with Fingerprint Reader and Touchpad
- 320GB 7200RPM
- 9-cell battery
- Bluetooth
- Intel Centrino Advanced-N + WiMAX 6250 Wireless
And I've found the following x201s at J&R online or via some eBay sellers:
- Core i7 640LM
- 12.1" 1440x900!
- 4GB 2DIMM RAM
- TrackPoint with Fingerprint Reader and Touchpad
- 320GB 7200RPM
- 6-cell battery
- Bluetooth
- Intel Centrino Advanced-N 6200
If I purchase the x201, I'll do a clean install of Windows 7 Pro (at least). I might leave the x201s with its native Windows 7 Pro installation, provided it's 64-bit. If SSDs become cheaper down the line, I may also swap one in. Also in the case of the x201s, I'll be purchasing an aftermarket 9-cell for better battery.
My main quandary is comparing the i7 620M and the i7 640LM. I understand the 640LM is a lower power processor, thus using less battery life. Yet it runs at a decent clock rate (2.16 GHz vs. the 2.66 of the 620M). Both have the same amount of L3 cache. I'm wondering if anyone can provide me with additional info and help me choose which processor is best suited for my needs.
Even if the 620M is significantly better, the 201s also features the WXGA+ 1440x900 screen, which I think is pretty crucial. The lighter weight is also a bonus, since I will be carrying it with me every day. I don't think that the higher weight of the 201 is that much of an addition, though. Lastly, can anyone comment on the 201 configured with the Intel Centrino Advanced-N + WiMAX 6250 card vs. the Intel Centrino 6200 in the 201s?
Thanks for any assistance you guys can provide me with.
