THINKPAD R40 P4M-1.8G 20GB 256MB XPH 14.1-XGA DVD/CDRW
Is it a good deal or can you get something cheaper and better .. or at least better for the same price?
Some people have told me that 14.1 screen is not big enough, but I think it’s ok. Any thoughts?
nah it s a good price for a pentium -M :), lekin i should sugest to look for a centrino laptop/notebook :)
How does performance (speed) of Pentium 4 M compares with that of Centrino? I think the current offerings in laptops come with 3 GHz max in Pentium 4 M, but only 1.6 GHz in Centrino.
If long battery life was not an important factor in buying a laptop, which one would be a better buy in terms of performance?
Is Pentium 4 M different from Pentium 4? 
yes, P4-M is specially made for less power use 
So f.e. if your gonna type a letter it ll use only 500 mhz but if you start gaming after it will use full processor power 
and besides that, they use less power.----> a p4 @ 2.0 ghz will use more battery power then a P4-M 2.0 Ghz.
If you want the top of the bill, buy yourself a Pentium-M. Not a P4-M
A Pentium-M @ 1.6 ghz is just as fast as a P4-M @ 2.2 Ghz.
lying beneath the Centrino, including the Centrino Mobile Technology, is a combination of the new mobile processor Pentium-M (codenamed “Banias”), the new Intel 855 chipset family (“Odem,” “Montara-GM”), and a WLAN adapter in mini-PCI format called Calexico, which is based on the 802.11b/a standard. Only notebooks with this whole package have Intel’s approval to carry the name ‘Centrino Notebook.’ As soon as one of the above is missing, it ain’t Centrino no more.
And a centrino laptop adds wireless stuff to it.----> prognose of a magazine, in 2007 80 % of laptops will be with an Intel Centrino

Centrino does nothing :) it adss only wireless abilities to it. you are confusing a Pentium-M and a Pentium 4-M.
average pentium-M uses 500-600 mhz less speed and is still just as fast.
but for the rest your correct, the Pentium -M is only available @ 1.6 Ghz max, while the P4-M is available till 3.0 Ghz I think
So for performance only???
The P4-M cuz it s availabe at higher clocks :)

Praetextatus - thanks for the info.
I visited Intel's site to do the comparision and surprisingly found similar results where Centrino (even with lower clock speed) had comparable performance results with that of P4 M.
