Lenovo has updated its low cost S-series IdeaPad laptop with three new touchscreen models. The laptops are all small portable 11.6-inch models and Lenovo promises up to 6-hours of battery life. The least expensive model has an AMD E1-2100 APU, 2 GB of RAM and a 500 GB hard drive. The IdeaPad S215 is priced at Php17,990. As far as I know, this is the cheapest Windows 8 touchscreen laptop in the market. I would probably pass on this one though.
The Intel Celeron 1017u equipped IdeaPad S210 costs a fair bit more, at Php21,990. The Intel Celeron processor is almost three times as powerful as the AMD E1-2100. The IdeaPad S210's comes with 4 GB of RAM.
The IdeaPad S210 also comes in a Intel Pentium 987-equipped model at Php23,990. I am not sure if the Intel Pentium 987 will give better real world performance though. The Intel Celeron 1017u seems to perform just as fast, and the Intel Pentium 987 actually benches lower.
