Rainy Day and DECT phone


The picture above was taken on the way back from East Coast. Have wasted a trip. Didn't windsurf because it was raining, and more crucially and excruciatingly , the wind was pathetically weak.

Actually had a chance to go yesterday, but have postponed the trip till today, hoping that the weather would improve - an obvious mistake - yesterday was better.

Lesson learnt : We are at the mercy of the weather and nature. Look at the Asian Tsunamis, Katrina, the JB flood ... time and tide (and weather) wait for no man - should have been there yesterday, ouch . But that would be impossible to predict - And, the weather forecast sucks!

Anyway, I am counting my blessings. Ended up shopping, have some retail therapy - bought an olive oil Loccitane cake soap to soften the pain ( and soften my skin, literally); and a DECT phone.

Have tried it and the result is amazingly better than the convectional cordless phone ( range about 100m for good models, my old phone was worse: I couldn't get a good signal from my bedroom). I can now talk over the phone at the bedroom, kitchen ... The box claims that the DECT phone's range is 300m.
