Prices are RSP, negotiable.

It's an Ivy Bridge duo core Celeron. TDP at 17W, yes, frugal on battery drain.
Definitely enough for "normal" usage, e.g. surf net with multiple tab (RAM will be a bigger concern, slap in more RAM if you can, 4G stick ~ RM100), MS Office, flash gaming, play music / video (can process FHD, just need to connect to external display).

Direct replacement is the Haswell Celeron 2995U, TDP at 15W, more frugal, but not yet found in lots of model.

Some of the models listed already have W8 pre-installed. For those FreeDOS spec, if you are with education institution, can get cheap legal Win OS.

Delivery mode typically is through DreamSpark.
Example, UM.

UM students will get a login from school admin, then can go to this site and download the OS.
Different uni who has tie up with MS (almost all reputable uni has) will have a different site.
Each login (unique to each student) can only get 1 key. So don't share

As I said, the thing with Dell is not about "durability", it's about their warranty support service and return policy.
If you buy a laptop from Dell, and opt for their standard on site warranty support, if there is any hardware problem, call them, and technician will be at your door within couple of days to fix it for you. This is true as long as warranty period is in force. Don't need to send to SC. So the idea with Dell is extend the warranty period, ideally to 3 years.

Personally, for laptop, I only buy Lenovo Thinkpad and Dell (any series) for family members (except that one time when my cousin insisted on MBA ) since their top notch on site warranty support ensure that aunties / uncles never bug me

Some users believe certain brands are very durable. But machine failure is a matter of statistics, and it will happen, the question is percentage. If user happen to get the lemon unit, then it all fall back to warranty support. And nobody want to deal with SC from hell   (you can find 1 thread right here in LYN talking about that  )
