Re:update?

A bit slow around here. But I have some updates. I dropped the Vaio. Heard it was too buggy for NLE. I'm now looking at 2 different Acer Aspire. The 1711SMi(17" 4:3, 2.8Ghz P4, 512Mb, ATA100 80Gb 7200rpm), it looks really good from the specs and is the only one I could find with a 7200rpm HD. It also has a 1000mbps network card which will be useful when I'm burning DVDs in it which were edited on my desktop. It will go much faster, I would guess. The memory is alos standard desktop memmory(cheaper to upgrade).
The down side? It's huge (15"x 12.6") and weights a ton (15.6lbs)
The other option is the Acer 1662 WLM (15.4" 16:10, 3.0Ghz P4, 512Mb, UltraATA100 60Gb, not sure if 5400RPM or 7200RPM. Are all UltraATA100 7200RPM?) and it costs 300 bucks less, the battery last about 1/2 hour longer and weight half of the weight. The down side is smaller screen(althought since it's widescreen, it doesn't seem that much smaller), not sure if the HDD is 7200RPM, the network card is a 100mbps only. I'm really undecided between the two, but it most likely will be one of them. Also looked at a Toshiba Sattelite P10-824 and a HP pavillion ZD7167EA, but wasn't impressed. Any opinions?Thanks
