CULV processors performance ??

Hi all,
I am having a pretty difficult time finalising a portable laptop Sad

I have just begun a phd in anthropology, and will do lots of word processing, music/movies, internet, and occasional photo editing.
Hence, I was initially confident that I would be able to decide easily between the satellite T235 and the portege R700.

After some initial research I focused on the T235. Here unlike the portege the battery life is pretty good, has a nice keyboard, does not heat, and its acceptably light (I want a less than 2 kg machine).

So what prevents me from finalising this one? This has to do with the low voltage processor which is a CULV U5400 1.2 GHz.
Now my simple query is ? how good is this processor from the point of view of my usage?
What I mean is will the T235 become sluggish if say I am working on the word processor, playing music, downloading through torrents, and have say a couple of applications open while I do this?

Right now, I have a A200 which has only 1 GB RAM and a core duo 2.0 GHz processor. I use this with XP and Ubuntu 10.04 and the speed is pretty much ok for the tasks at hand. Can someone compare the T235 with the A200? That way I would have some idea of the real world performance and not simply a comparison on paper which reveals very little of how the machine will feel in day to day use!

What I would hate is to see the hourglass when I am opening an application/window. The minimum I am looking for is snappy performance where windows and applications open with a minimum of delay.

The performance you write about

Has little to do with the CPU but more to do with the transfer time from the hard disk to memory. Something like 99% of the delay in starting an app is the amount of time it takes to get the program off the hard drive and into memory.

Not a CPU issue.

so what does it depend on ?

thanks Bob!
so how can i expect to have the T235 perform ?
and if performance has little to do with the CPU, then what does it depend on ?
the time taken to get programs from HDD to RAM - what does this depend on ? and how will the T235 fare in this dept vis-a-vis laptops with i3/ 5 etc processor ?

We covered that.

Disk to ram transfer speed is too much of the time lost in launching an app. You'll find folk ask why apps launch faster the second time (the answer is "cacheing."

This is a typical dual core pentium. It will perform fine. But why not test drive the machine first? And to compare to the i3/i5 is a tad unfair. You jump the GHz and add Hyperthreading so no contest save the amount of time to launch the app the first time.
