After having extremely high hopes for the Dell Mini 12 and being sorely disappointed (small PATA HD, hard-wired 1gb ram), I'm currently VERY interested in both the Gateway L3103u and upcoming Acer AO751 6-cell models. In comparing the two, it looks like you're basically trading faster FSB and Video Decoding (Gateway) for ~30% better battery life (Acer). Since one of my main uses will be 720p MKV video files, video decoding is up there on my priority list. This, along with the fact that it's available now, has me leaning heavily towards the Gateway. If I can dig up the $50ish in rewards zone certs I have somewhere and maybe a 8-10% coupon, I'll probably pick up the Gateway in the next couple of days.
