I was thinking about getting the T40 then I noticed the T41. The T41 seems to be a lot cheaper than the T40 by a few hundred dollars, but it also seems to have more things.

The T40 has PC2100 memory, but the T41 has PC2700
The T40 has XGA Resolution, but the T41 has SXGA
The T40 has a Radeon 7500, but the T41 has a Radion 9000
They both have the same Harddrive and the same dimensions.

So why is the New T41 so much cheaper but it seems to have better things in it.

Just depends on your config for the t40
My T40 has the Radeon 9000 and the SXGA screen
also the T40 comes with a 3 year warranty and the T41 1 year
the T41 does have the PC2700 however

The T41 has a three year warrenty. The T41 is still cheaper than the T40 even when it has better RAM.

well the last one on the list has a 3yr warranty the other 2 have 1yr.
still don't know why they are still cheaper
maybe lower quality products somewhere
or just the old depreciation of technolgy.

The only material difference between the T40 and the T41 is the inclusion of a special sensor on the T41 motherboard that detects if the notebook is falling. The sensor, coupled with IBM software, will theoretically park the HDD heads fast enough to prevent damage to the drive.

A T41 is not necessarily more expensive or cheaper than a T40. It depends on the configuration you choose. I am pretty sure that the T41 will replace all T40s at all price points eventually.

i bought my T40 in august. for 1600$ with the stock discount. now the T41 with a slightly faster pm costs about the same money.

aside from those 3 points is there any difference in the actual build?

aynone know what the current stock holder deals are? i called IBM the other day to get the new offers key but they wanted me to fax them proof of ownership and im too lazy to do such.

i still love my T40 alot. this thing is going last me a good long time. when i buy another laptop it's definatley going to be a T100 +/- 20.

Another question, how much is the employee discount? Is it the same as the stockholder one?

Thanks.

Oh and the T41 also has a technology where it can sense if the laptop is accelerating and stop reading the Harddrive it to prevent damage on impact.

wow, that is fancy shmancy. the t40 hard drive is shock mounted correct?

Something stange happen today. All of the New T41s are now 11% off.

Look at this

A T41 with a 1.6 Ghz Pentium M, and 256 MB of PC2700 Memory is over $200 Cheaper than a T40 with a 1.4 Ghz Pentium M and 256 MB of PC2100 Memory. Eventhough everything else is the identical on both machines. This seems really strange to me.

That is marketing to counter the "informed" joe six-pack effect --- "I read a few reviews and I want an IBM T40 not an IBM T41, what are you trying to pull on me?"

I think I figured out the price difference.
The T40 Memory might actually be faster. Even though the T40 is only PC2100 Memory it is CL2 while the T41 PC2700 Memory is CL2.5 which is slower then CL2. So how would PC2700 CL2.5 compare with PC2100 CL2.

I also found out the T40 40 Gig Hard Drive is the Hitachi DK23EB while the T41 is the 5K80 which on specs seems better.

Some differences betweent he Hardrives are this.
T41 8MB Buffer, T40 2MB Buffer
T41 ATA-6, T40 ATA-5
T41 Max Density of 70 Gb/in^2, T40 38.5 Gb/in^2
T41 Media Transfer Rate: 450 Mb/Sec, T40 352 MB/Sec
T41 Average Seek 12ms, T40 13ms
T41 Average Latency 5.5ms, T40 5.4ms

So it looks like the T41 Hard Drive is faster. So why is it so much cheaper.

It all depend on the specification and the promotion at a time. The memory in the T41 is indeed PC2700 but it won't help much because the P-M chipset is designed for the PC2100. It is like put the PC133 SDRAM on a motherboard with a CPU that only use PC100. It is mainly marketing attempt to make the spec look better with minimal cost increasing. As for the spec, the T41 should be identical to the T40 except the HDD airbag thing in the T41. The T41 is cheaper because it just natural to be cheaper. Imagine IBM released T40 6 months ago, do you expect them to release T41 with almost identical spec with the same price they were 6 months ago? Note that it is IBM tradition to not lower the price of each model too much but rather release a new model with a comparable spec with cheaper price to lower the price without lower the value of their laptop (it may sound confusing but it is always like this with the high-end stuffs).

For example, My T40p cost $3.5k without any discounts when it is first released. I was able to get it for about $2.5k with accidental damage protection warranty and considered that as a very good price. With the current promotion from IBM, you can probably get a comparable spec T41 for less than $2.2k (with damage protection warranty) except they don't have FireGL in the T41 yet (only existed in the paper for now). And the FireGL part cost at least $300 more because it is profesisonal gfx.

If you want to get a good laptop, this is probably a good time to get the T41 since it pricing is very competitive (after promotion and/or discount). The machine is simply the best currently available. For me, I will stick with my T40p for th enext 3 years =) The thing have everything I want for a laptop in a compact package.

Actually the Pentium-M and 855 was built to handle both PC2100 and PC2700. A PC2700 will run at 333MHZ in the laptop not 266. So their should be a gain in proformance. Also as I mentioned the Hard Drive are also different. The T41 uses the newer Hitachi 5K80 while the T40 uses the older DK23EB, note this is only for the 40 Gig Hard Drives.

If you look at my post above you can see the difference between the T41 and T40 Hard Drives. Will their be any noticable proformance difference between the two hard drives.

The 5k80 might be a little bit faster because it have higher arial density. But if the HDD have the same size, the differences will be small. I'm not sure about the i855 but AFAIR the i855 was built for PC1600 and PC2100. This is from my memory when I first read the Intel white paper about 6-7 months ago so it might be wrong. I think they have two flavors at the time, i855 and i855GM (not sure about the name here). One is the normal P-M chipset (i855) with PC1600 and PC2100 support. Another with the integrated gfx core. So unless, things change or I remember wrong, the i855 use PC2100. Also, it should be noted that it also depend on the OEM as well whether they make the MB to utilize the PC2700 or not. Good example is the Sony Vaio GRX500 series. The chipset (i845 I believe) supports PC2100 but the Sony MB doesn't fully support PC2100 so the RAM is run at 200MHz max.

Just want to add something. The published max arial density is probbaly for the 80GB version (in the case of 5k80 HDD). For the 40GB version, the arial density will be lower than that number.

I ordered a T41 about a week ago, its still about 25 days out according to IBM. It is a fairly high end model 23739FU with an addditional 512mb of ram. I have never owned an IBM before, so when I get it I would be glad to benchmark it and post the results. What impressed me with this model is it came with the modfications I wanted to add already except for a 9600 video card. The hard drive is the new hitachi 7200 rpm 60gb drive and they finally added the 1.7 ghz centrino. I am replacing a Toshiba Portege 2000 which although around 3.3 pounds with 2 batteries, can not handle large files.

How do you guys like the SXGA resolution on the 14" display? I'm planning to get one of these in the next few weeks. Trying to figure out how to configure it the best way for my needs.

Thanks.

I have the SXGA screen and I can not imagine the XGA on this
I have a 15 in Flat panel on my desktop and after using the Lappy for a while
my desktop screen looks blury and until I started using the SXGA it looked great.
