If you're looking for a powerful desktop replacement notebook, you could go the conventional route and select something like Dell's Dothan Pentium M-powered Inspiron 8600c. Nothing wrong with that -- we gave it an Editors' Choice, after all. But if you want similar power plus a degree of future-proofing, why not consider a notebook powered by a 64-bit CPU that can also run today's 32-bit operating systems and applications very speedily? Enter Acer's Aspire 1502LMi, the top-end model in a range based around AMD's Athlon 64 processor -- in this case, the 2GHz 3200+ part. With 64-bit Windows due later this year, and applications certain to follow in due course, you'll be in pole position as mainstream computing moves into a new era.
