Downloaded and installed Beta 1, and I’m very impressed so far! I’ve tried every speed “boosting” caching app out there (O&O Cache, Cacheman, CacheXP, and countless others). Eboostr outshines them all and provides very noticeable speed improvements. No problems at all so far with on a Intel Celeron Mobile (1 GHz) laptop with 1GB of Ram, using an OCZ Rally 1gig USB flash drive (960 mb cache) and a 512 mb PNY Sd card (488 mb cache). On to Beta 2! Nice work, team!
