Well, I don't know what you plan to use these for, because that's probably the defining factor. I have had my ThinkPad for a long, long time, and don't see myself replacing it any time in the future [unless I get something with a tagged TLB to do some porting]. The great thing about it is that it goes where I go- I don't have to sit at a desk, I can sit on the floor, on the roof, take my computer into the kitchen, etc. Not to mention, it sure feels solid. I've considered buying a newer laptop, but most of what I've seen feels a bit flimsy by comparison. I'd definitely have to go Lenovo again if I bought a new laptop.
Of course, if that doesn't apply to you, don't listen to me
you can get much better graphics options on desktops. I might even buy a new desktop just to use CUDA.
was put impeccably into words at DebianDay for me last Saturday, by Knut Yrvin of Trolltech - adults try something once, fail, and then are like "ffs this doesn't work". Children try, fail, and then try again, and succeed - maybe on the second, or even fifth retry. But the thing is that they keep at it and overcome the problems in the end.
